  1. Angela,

    You are quite welcome!


  2. Bill,
    Thank you for taking the time to provide these steps. I just completed the process and in less than five minutes I’ve connected our outlook to yahoo. These steps are well documented with enough details anyone can easily complete the task.
    Thank you!

  3. David,

    I think the problem here is with your All Account Group, which is Outlook 2010’s main Send/Receive Group. To learn about this stuff and get your Yahoo Plus mail sending and receiving automatically, check out the page I just put together on the subject: http://living-with-outlook-2010.com/emailaccounts/2011/02/sendreceive-groups-working-with-your-all-accounts-group/

  4. Bill,

    I have my Yahoo Plus mail set up in Outlook 2010, but it doesn’t have “push” capabilty like my other Exchange account does. For example, if I send an email to my Yahoo Plus, I must first click send/receive in order for it to show up in the inbox. I can’t figure out how to get “instant” notification of new email.

  5. Bill,

    I see what you meant.

    I downloaded all my Yahooo emails onto Outlook and have realized that when I delete messages from Outlook the deleted emails still show up the Yahoo (online). The lack of syncronization of POP3 can cause a lot of confusion.

    I am going to advise my coworker not to have Yahoo on his Outlook.

    As for me, I am going to migrate all my personal emails to gmail instead.

    I have to say that I am really disappointed with Yahoo, and wish I didn’t pay for that $19.99 to upgrade to MailPlus. 🙁

    Thanks again for your kind help.


    I have dow

  6. Bonnie,

    Thank you for you kind words.

    When you say the iPhone stopped working, do you mean that your coworker couldn’t see new messages on it? If so, that’s because Outlook is downloading the messages and removing them from the Yahoo mailbox. It does this to prevent there from being two separate copies of the messages, one in the Yahoo mailbox and one in Outlook. That’s because the POP3 protocol that Yahoo uses doesn’t support two-way synchronization of messages.

    Assuming this is the situation for your coworker, what they can do is go through the directions again. At step 19, set the “Leave a copy of messages on the server” checkbox and see if that clears up the problem. Your coworker should realize however that what they do with their mail on the iPhone will not be reflected in Outlook and vice versa.

    I hope this helps.


  7. Bill,

    Thank you very much for putting this information up. You are a life saver!

    I have no problem setting up my Yahoo Mail Plus account to work on Outlook 2011. But my coworker, who has a yahoo business account, doesn’t seem to be able to do it. We followed the instruction above and an automatic test message was sent to his Yahoo account confirming all is good to go, then his Outlook and iPhone stopped working (can’t receive any new incoming emails).

    We deleted the yahoo account on his iPhone and re setup, but to no avail. When we went to Outlook to delete the yahoo account the iPhone started working again.

    Any idea?

    Thanks in advance!

  8. Mark,

    What I’m seeing on the boards is that RCN has put some kind of limits on access to their SMTP server, which could give the results you describe. I suggest you try using SMTP2Go to see if that allows you to send. They provide an SMTP service that always works, regardless of what an Internet Service Provider might do.

    SMTP2Go has a free 7-day trial right now, and costs as little as $1.99/mo., so might be an affordable solution to the problem you are seeing.


  9. Hello Bill,

    First of all, thanks for helping us all out, much appreciated.

    I purchased Outlook 2010 last week so that I could copy some of my emails from my work onto my home computer. I added a gmail account along with my yahoo address to the Outlook service, but the yahoo email does not send emails, but does receive them. I went through your 25 steps but still receive the “Send test e-mail message: the connection to the server was interrupted. If this problem continues, contact your server administrator or internet service providor (ISP).” message.

    At this point if I need to reply to a yahoo email, I go back into yahoo itself to do so. (since the test service never worked, clearly my yahoo emails are staying in that domain and are not being deleted once read in Outlook)

    I use RCN as an internet provider, and am having success sending and receiving via gmail on Outlook 2010, but stuck on the send emails on yahoo, and yes, I have yanoo mail plus.


    Thanks, Mark

  10. Gerald,

    I see what you mean about that Yahoo help page! Nothing of value there at all.

    Can you walk through my instructions again and confirm that your settings match Step 22 and 23 of the instructions? The error message you are getting is related to the SMTP server, and those steps contain the settings that normally work. However. some Internet Service Providers completely block access to their SMTP server when you are not directly connected to their network.

    If your setting match those in the instructions, you will probably have to use an SMTP service. The one I recommend to people is SMTP2Go, an SMTP service that works worldwide. Right now, they have a 7-day free trial and reasonable monthly rates (as low as $1.99). To test their service, click here.

  11. Bill, I also received this message when I used the “test account settings by clicking the next button,” it said, “send test e-mail message: Cannot send the message. Verify the e-mail address in your account properties. The server responded: 530 authentication required – for help to to http://help.yahoo.com/help/us/mail/pop/pop-11.html” I went to this website, but found no helpful information. I hope this helps further pin down my problem.
    Thanks again.

  12. Bill, I am having the same problem as Heather. I have gone over your tutorial several times, but I am still unable to complete the process. When I get to the “test account settings” stage, a new window pops up and says “enter your user name and password for the following server.” My user name and password are correct for my Yahoo email account, but when I click “OK,” this window goes away for a few seconds but pops back up again. When I click the “cancel” button, an error message says, “Send test e-mail message: Your e-mail server rejected your login. Verify your user name and password for this account in Account Settings.” I have upgraded to a Mail Plus account, so what am I doing wrong? I can browse the web normally at home, I have had no trouble to date accessing my Yahoo mail account, and I have no other accounts configured with Outlook. Any help will be greatly appreciated! Thanks.

  13. Stacy,

    Did you try the instructions on this page:


    I know they are for earlier versions of Outlook, but want to be clear on where we’re starting from for this.


  14. Thank you very much. Works like a charm. Thank you!!!!

  15. Stacy Malinow | January 9, 2011 at 10:19 pm |

    Thanks again Bill. Our internet service provider is Cablevision and I am trying this from home.

  16. Stacy,

    Can you tell me who your Internet Service Provider is and whether you are trying this at home or at some other location? It sounds like your service provider has changed the settings for sending email. Many of them have done this to reduce the chance that unscrupulous people will log into their networks to send junk email. Unfortunately, when they make those changes, they sometimes end up messing up existing customers.


  17. Stacy Malinow | January 8, 2011 at 12:50 am |

    Thanks Bill. The message I got read “Sending reported error (0x80042109) ‘Outlook cannot connect to your outgoing (SMTP) email server. If you continue to receive this message, contact your service administrator or Internet service provider.”

  18. Heather,

    In researching this, I’ve seen some other folks having similar problems with Outlook 2010 and passwords (but not necessarily Yahoo accounts). Let’s start from the most basic and see if we can figure this out.

    Can you browse the web normally when at home?

    Do you have any email accounts configured on Outlook 2010 that do work successfully at home?


  19. I have tried this for 3 days now, and my Outlook 2010 will work with my Business Mail when I’m on the wifi connection at work… but not when I’m at my wifi connection at home. It says that my password/login is rejected, and I keep getting those pop-up boxes asking for my password. Any ideas?? I need to be able to work from home!

  20. Stacy,

    I’m confused by the fact that the test passed but the mail won’t go out. Can you click the Send/Receive tab in the Ribbon, the Send/Receive All Folders button and let me know if the messages get sent?



  21. Stacy Malinow | December 27, 2010 at 6:55 pm |

    I have Yahoo Plus and used to use an older version of Outlook Express. My husband upgraded to Outlook 2010 and now I can no longer send emails through Outlook. (I can receive them without a problem.) The strange thing is the test email will work and I can send emails through this account using my Blackberry. Do you have any idea how to fix this?

  22. Annatjie,

    It is impossible to say with the information I have so far.

    Can you log in to your Yahoo Mail Plus account using the web interface?

    Are you doing this at work? Some companies block Outlook/Exchange access to external mail services like Yahoo Mail.

    What information (if any) does Outlook provide when the test fails? Does it indicate if it is failing on sending, receiving, or both?

    With this information we will have a much better shot at fixing the problem.


  23. Hi Bill,
    I am a plus account holder and have just bought the 2010 office license I have entered your steps about 4 times and the test message failed every time!!! what am I doing wrong???

  24. Please I need some help on this problem I have. I upgraded to Yahoo Plus last night and set up Outlook 2010 according to the listed procedures. All the 26 steps went through fine. The test in step 25 was successful and I see the test email from my Yahoo inbox. However, I tried send/receive many times and I do not see any email got downloaded into my outlook inbox. Show Progress always show sending and receiving successful everytime I do a send/receive but there is just no email get downloaded at all. I can see many emails in my Yahoo inbox. What can be wrong?

  25. THANK YOU, THANK YOU, THANK YOU, THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    May God Bless you for your knowledge and in freely helpiung others. It took me 5 hours of fidgiting with this before I found this page. Your instructions are dead on and worked the first time. Thank you again!!

  26. I figured it out. I forgot to select “SSL”. Thanks Bill!

  27. I upgraded my Yahoo! account but still get the following error message; “Send test e-mail message: the connection to the server was interrupted. If this problem continues, contact your server administrator or internet service providor (ISP).” How do I fix this problem?

  28. Thanks for the input, but we’ll have to agree to disagree on this one. I’ve done it the way you describe before, with a copy of the message remaining in the Yahoo Inbox, and it leads to muc confusion. The reason is that you then have two copies of every messages, and those copies are not synchronized in any way. Here’s an example:

    You get an urgent message that you need to call the boss about the big project we’re working on for tomorrow morning. Outlook downloads a copy and leaves a copy in your Yahoo mailbox. You see the copy in Outlook, and call the boss. Hours later, after working hard on the project all day, you get home and decide to check the messages on your phone before bed. You see an urgent message that you need to call the boss about the big project we’re working on for tomorrow morning. You call the boss and wake him up in the middle of the night in response to a message you already responded to when you saw it in your Outlook Inbox.

    An overly dramatic example perhaps, but I know from my own experience how confusing it can get when you have messages in two different places that aren’t synchronized. And there’s the added hassle of trying to decide which messages you can delete in Yahoo because you already dealt with them in Outlook and vice versa.

    If you don’t trust your Outlook PST file and/or you want to be able to get at your messages from multiple devices, you are better off using an IMAP capable email provider like Gmail or GMX mail, or getting your Yahoo mail connected to a Hosted Exchange account.

    I hope this clarifies my reasons for advising people not to leave mail in the Yahoo mailbox.

  29. Rachel,

    I’ve never tried setting this up with a trial version of Outlook 2010, but offhand don’t see why it wouldn’t work. To help, I’m going to need more information.

    First, can you log on to your Yahoo Mail Plus account and send and receive messages normally?

    If so, what happens when you hit step 25 and click “Test Account Settings?”

    Once I have this information we can go from there to try to get your connection working.


  30. Gwynne,

    When you can receive but not send emails, either the SMTP settings aren’t right, or your ISP is blocking your connection. Since you tried setting it up several times, I’m going with the latter explanation. I suggest you read the information about SMTP relays on our sister site: http://www.living-with-outlook.com/smtp-relay.html and give that a try.

    Let me know if it works and if not we’ll try something else to get you going!


  31. I have tried this several times. I have a Plus account and I can recieve emails, but outbound emails won’t transmit. When I use the set up as described I get an error message when connecting for outgoing and get told to contact my ISP. Special.

  32. Thank you!

  33. Since you are using Yahoo.co.uk, different rules apply to you than to US users. Have you tried configuring Outlook to work with your free Yahoo.co.uk account?

  34. So why is it that I am able to retrieve my Yahoo Free messages to Outlook Express and Thunderbird?

  35. Bill,

    1. The Outlook 2010 / Yahoo Plus connection has never worked with out displaying this error in the send/receive dialog. The odd thing about this situation is I am actually receiving my email.

    2. I have an Windows XP and Windows 7 machine and both are displaying the same error message in the Send/Receive dialog. I have the XP machine configured so Outlook 2010 is configured to only communicate with Yahoo. The Windows 7 machine is configured so Outlook 2010 gets mail from my Yahoo Plus and Windows Live mail accounts. The Windows Live mail is working without displaying any errors.

    3. My ISP is Clearwire. The XP machine is directly plugged into my router while the Windows 7 machine communicates wirelessly. As an experiment I plugged my XP machine in directly to the Clearwire modem and I got the same error.

    An aside:

    Currently I am using the free Zimbra client to get my email from yahoo and it works perfectly with either the free or paid version of yahoo mail. The really great part is that it communicates both ways with my yahoo contacts and calendar. To eliminate a potential conflict between Outlook 2010 and Zimbra I still get the error even when I close the Zimbra client and shut down the associated service.

    Thanks you so much for you help!



  36. Kate,

    I’ve not experienced this problem myself, but have found some information. The following questions should help us narrow this down:

    First, has this connection ever worked for you? That is, have you ever successfully received email from that account in Outlook 2010?

    Second, do you have more than one POP3 account connected to Outlook?

    Third, what is the name of your Internet Service Provider (ISP)?


  37. I am getting this error while sending and receiving from my Yahoo Plus account using Outlook 2010:

    Task ‘[email protected] – Receiving’ reported error (0x800CCC90) : ‘Your incoming (POP3) e-mail server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP). The server responded: -ERR problem retrieving message.’

    I am quite stuck at to solve this problem. Any hints, help, or solutions will be greatly appreciated. Thanks!

  38. Thanks Carl! Glad to help. I’m a big fan of that sleeping stuff myself.

  39. Life saver…now I can sleep!

  40. Christina,

    There are two separate issues in your message. Let’s make sure we are clear on the high-level one first. Outlook can’t really sync with Yahoo Mail. Because Yahoo only supports the POP3 mail protocol, the best we can do is copy messages from your Yahoo mailbox over to Outlook. We can also reply to those messages, or compose new messages, and send them out using your Yahoo Mail email address. But we can’t sync Yahoo and Outlook so that your messages appear in both places, and whatever you do to a message in your Yahoo mailbox automatically gets carried over to your Outlook Inbox and vice versa.

    Now as far as what happened to the messages in your Yahoo mailbox:

    It sounds like the messages were copied over to your Outlook Inbox because they get deleted from your Yahoo mailbox after that. Can you check your Junk mail and Deleted Items folders to see if the messages ended up in there somehow?


  41. After completing your helpful 26 steps, I’m still unable to access my yahoo emails in the outlook inbox. The outlook inbox is empty. In addition, all of my emails within my yahoo inbox have been removed. How can I keep my yahoo emails as my default and have them sync with outlook?

  42. Charles,

    That message implies that you haven’t upgraded your free Yahoo Mail account to a Yahoo Mail Plus account. If that is true, then you should go to the section of this page titled, “Convert Your Yahoo Mail Account to Yahoo! Mail Plus” complete that upgrade, then try the process again.


  43. unable to login to the yahoomail from outlook 2010

    Log onto incoming mail server (POP3): Your e-mail server rejected your login. Verify your user name and password for this account in Account Settings. The server responded: -ERR [SYS/PERM] pop not allowed for user.

  44. Thankyou! Every step is clear and most importantly…works.

  45. BC,

    Glad to help!


  46. Yahoo only allows POP3 connections, which only allow you to pull messages out of the Yahoo Mail Inbox. It doesn’t allow for a full sync of the folders.

    You can, however, leave copies of the messages in your Yahoo mailbox instead of deleting them after Outlook downloads them. It is step 19 in the instructions. Set the “Leave a copy of the messages pm te server” checkbox to do this. Be warned that it can get confusing, since you end up with 2 independent copies of the same message.


  47. BC McCulloch | August 25, 2010 at 3:17 am |

    VERY WELL DONE!!!!!! I just followed the step by step instructions on linking biz mail at yahoo to outlook 2010. The first time I tried it, it did not work, but I must have made some input errors. So I went back in, carefolly step by step and WOW!!!!! It worked. great job, and thank you!!!!!!!!

  48. Jim,

    It sounds like you really want to sync your Yahoo and Outlook email accounts. Unfortunately, you can’t because the protocol (POP3) that Yahoo uses to communicate with Outlook and other email programs doesn’t support any of those abilities.

    The way I deal with this is to do everything in Outlook. I send and receive from Outlook, and use Outlook to do all the sorting, organizing, and managing. More specifically, I have my Exchange server extract messages from the Yahoo Mail Plus Inbox and then work with them through Outlook. Because I am on an Exchange server, I can use Outlook remotely and use Outlook Web Access when I don’t have access to my own computers.

    Sorry I don’t have a better answer for you.


  49. Jim Prusa | July 30, 2010 at 3:24 am |

    This worked fine for my Inbox. Thank you. HOWEVER, how can I download all other folders? This is the big problem. I need to download the Sent and all other created folders. Ypops seems useless.

    Also, is there a way to sync? My outgoing Outlook messages do not show up on the Yahoo Email once I send them.

  50. Thank you! Your site was the only one even remotely helpful getting my Yahoo account to talk to Outlook 2010 (quite similar to your Outlook 2007 instructions). You even had the correct incoming and outgoing servers where others told me to ask my ISP, ugh. Switching the SMTP outgoing port from the default 25 to 587 solved it all and I am up and running thanks to you.
