  1. Low Man,

    I’m not a Mac guy so I don’t know all the details, but here’s what I’ve learned in my research. There is at least one program/service you can buy that claims to give you access to your Yahoo Mail on the Mac using the IMAP protocol. IMAP would map all your folders, and synchronize messages between Outlook and Yahoo. I’m assuming this service works by tricking Yahoo into thinking your Mac is a mobile device, because Yahoo does not support IMAP for desktops and laptops, but I’ve read that you can get IMAP on mobile devices.

    There is a PC program that tries to do the same, but it has a reputation for being unreliable, which is not something you want to say about your email.

    In short, POP3 is the only Yahoo authorized way of getting email from Yahoo Mail into PCs running Outlook or any other mail client, and that protocol doesn’t support things like folder sync.

    I hope this helps.


  2. Maybe you can answer my question. I have setup my yahoo mail in my Outlook 2010 I can send and receive email just fine but how come my folders I have setup in my yahoo mail are not transfered with my filters and settings. I setup my yahoo mail on my Mac and all my folders were setup on my Mac mail why not Outlook 2010

  3. The type of connection Yahoo uses doesn’t allow for changes you make in Outlook to be reflected in Yahoo. The POP3 connection they use allows you to download messages from Yahoo Mail into Outlook, and optionally delete those messages from the Yahoo mail servers as soon as Outlook grabs a copy of them. Typically, people set up their connection so the messages get deleted from Yahoo as soon as Outlook grabs a copy to eliminate the confusion of having two unsynchronized versions of every message.

    There is no automated way to have a message remain on the Yahoo mail servers until you delete it from Outlook, then have it be similarly deleted from Yahoo. POP3 is an old, reliable technology, but it is built around the idea that you copy the mail into your email client (Outlook) and immediately delete it from the mail server (Yahoo).

    Sorry I don’t have any better info for you.


  4. Hi there,
    Such a userful Web Site! Thanks so much as it helped a lot. My question is this: I just set up Yahoo! email to load to outlook; however, it is loading it to a .pst file. What I want it to do is load to outlook and stay on the server until I move it into a .pst file/folder. Reason is that I want to delete items from Outlook and have them be deleted on the Yahoo! web-based email as well. Is this the correct approach? If so, how can I do this? I have searched the Web and can’t quite figure out how to do this.

    Thanks so much!!!

  5. Joey,

    That’s great to hear. I haven’t tried the setup you have. My Yahoo mail goes to a hosted Exchange server, and I connect everything to that. Connecting a smartphone like you have adds a little twist to things since Yahoo mail seems to work differently for smartphones versus desktop devices.

    Thanks for updating us on your progress.


  6. Hi Bill,

    I think I figured it out. I should have been paying attention to the options I was selecting rather than just blindly copying your instructions. I made the tweaks needed, and it seems to be working . . . . at least so far, so good.

    Thanks again for your great instructions.

  7. Hi Bill,

    Great instructions for connecting Yahoo email to Outlook. Everything worked like a charm!

    I have a question. Is it possible to keep a copy of my inbox in both Yahoo and Outlook where I can delete emails from my inbox in Outlook and it automatically deletes in Yahoo? The reason that I ask is that I like to be able to see my Yahoo inbox on my smartphone. I use Outlook on my laptop to manage my calendar using email invitations from friends using Outlook as well as to manage email when I’m at my laptop.

    Thanks in advance for your response.

  8. Thank you Christie! I am both an instructor and tech writer. Too much of the material online is written by techies, for techies, leaving normal people totally bewildered. I see my job to be making this stuff understandable and as easy as possible to work with. It shouldn’t require a degree in computer science to be able to view your Yahoo Mail in Outlook!


  9. This was the BEST accurate information I have ever looked up! This was so helpful and made easy to follow. I am so impressed! Are you an instructor or technical writer? Thank you for this very helpful information!!

  10. THANK YOU! This was an excellent fix. Absolutely nothing I could find on Yahoo’s sites would work. Again, thanks!

  11. Kate,

    People in certain countries don’t have to pay, but most of us do. Heaven knows why.


  12. Australian users don’t need to pay for POP access, i’m surprised anyone needs to. It’s always been free for me.

  13. That’s excellent. Now we have a couple of possible solutions to these Yahoo problem. Hopefully they will be enough until the underlying problems are fixed.

  14. EUREKA!
    Thank you, thank you, thank you dblr40!!
    I have had this same problem fror DAYS, and I tried every single suggestion on here and various other sites. It WAS the special character in my password that was creating the problem. Yahoo should fix this. They themselves recommend the use of special characters in passwords, and it is generally a good idea. My Yahoo account was hacked last year.

  15. I’ve discovered that something similar happened to Mac users a month or so ago.

    According to the thread, if you disable SSL for incoming and outgoing servers, then set the Incoming server port to 110 and the Outgoing server port to “Default” the connection will work again. I assume that on the Outlook side, this last bit translates to going to the Advanced tab in the Internet E-mail Settings dialog box, and clicking the Use Defaults button. I can’t test this as my connection is working fine.

    If any of you give this a try, please report your results back here. Whatever is going on appears to be on the Yahoo side and fairly widespread, so anything you can share could help lots of people.



  16. Don,

    You can’t get the folders into Outlook. Yahoo uses the POP3 protocol for connecting to PCs, which allows Outlook to copy messages out of the Yahoo Mail Inbox, but that’s it. Yahoo would have to switch to a different email protocol to support copying the folders or their contents, and that is unlikely at this point.

    I was able to send and receive yahoo mail from Outloook. When I performed the send and receive Outlook acquired all of my open Yahoo mail, but it did not bring in my mail folders. How do I get the yahoo folders into Outlook?

  18. Thanks for the info. There seems to be a lot of people having problems with their Yahoo Mail to Outlook connection recently.

  19. I started having problems with OUTLOOK 2010 downloading email from yahoo. OUTLOOK kept telling me my yahoo password was bad. I changed my password to the recommended yahoo password with special characters. That made it worse could not send or receive. I took the special character out of the password 2 nights ago so far so good. FIXED MY PROBLEM so far. It is possible the special character modified the code that OUTLOOK sends to yahoo. Hope this helps some one.

  20. I haven’t seen the User ID/Password problem, but yesterday Outlook suddenly informed me that it wasn’t activated. I went through the activation process again and all is now well, but neither I or the support guy could figure out why it suddenly decided it wasn’t registered. Is Outlook still acting up for you?


  21. Starting about 4 days ago, Outlook 2010 is prompting me for my Yahoo credentials. The pop-up is pre-populated with my username and password so all I have to do is click OK and it connects. This happens when OL has been running for hours and happens continuously. I checked my connection settings with the values you have above, then tested the connection (which connected and sent the test message).

    I have had OL configured for accessing my Yahoo plus mailbox for more than a year and this pop-up just started out the blue. I am able to login to my mailbox via the browser without issue.

    Anyone else having this issue?


  22. Seems for the past 3-4 days, my Outlook has been showing me the UserID and Password screen for connecting to Yahoo! plus mail via pop3. When this happens I usually don’t do anything because I know it’s on Yahoo! end; as always.

    However, this has been going on for too long now. Do you or anyone know of anything going on at Yahoo! Have the settings changed any? I know my settings are correct and were verified with this webpage, but maybe something changed very recently.

    Anyone having problems???

  23. Trajan,

    Is this problem still going on? I’m not seeing that kind of problem, even when logging on through multiple service providers in different areas, and I haven’t gotten any other reports of similar problems. Are you using the same ISP for all the tests? Perhaps they changed something on their end?


  24. Thank you a million times over! You are a life saver!!!

  25. No, there’s something more problematic going on. I have been using Outlook with Yahoo Plus for quite a long time, and several weeks ago sending mail stopped working, with the “connection to the server interrupted” error. I can still receive mail (POP), but cannot send it (SMTP). Outlook works perfectly when sending through other POP/SMTP providers. Furthermore, I can get Thunderbird to send mail with Yahoo from the same computer, so I know it is not an ISP port-blocking issue. Finally, I have tried using Outlook on a different computer, and also on a different Internet connection, both of which also failed. So there is something suddenly failing in the Outlook/Yahoo SMTP server interaction. I suspected an Outlook update broke something, but further experimentation has shown other broken clients, like Opera Mail, even though some other mail clients still work (Thunderbird and The Bat!, for instance). I think Yahoo changed something in the way their servers react to an incoming connection, maybe in the encryption negotiation or something (or supporting SSL vs. TLS), and it throws some clients off.

  26. It sounds like your ISP is blocking you from sending. They do this to prevent spammers from using their network, but it can mess up regular folks like you and me. The information on these Can’t Send Email pages may help.

  27. Raj,

    The POP3 protocol that Yahoo supports only allows Outlook to download copies of messages from your Yahoo Mail Plus account to the Outlook Inbox. It doesn’t support updating the Sent Items folder or any of the folders with information from Yahoo. This is a limitation of the protocol itself, and not something we can fix or work around.


  28. I have successfully updated and attached outlook, but when outlook updates it only updates the Inbox folder. The sent folder doesn’t update.
    Can you please help me with the same.???
    or someone suggest a solution to fix it??

  29. … I am getting the following error message in Outlook:

    Task ‘[email protected] – Sending’ reported error (0x800CCC0F) : ‘The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).’

  30. Bill

    I tried everyting that you had in your link:


    But still cannot send Yahoo mail from my Outlook 2010 client. I even tried the following:

    1) Do this on another computer running windows xp (my computer is running windows 7) setup Outlook and my account information, try to send, no luck

    2) Do this at my brothers house, my ISP is ATT his ISP is Comcast, no luck.

    Again, I can receive mail fine but cannot send.

    Any other thoughts?

  31. DT,

    Everything seems to be working fine for me. Anyone else seeing issues like this?

    You might want to check the advice on this page. It may help you track down the problem:


  32. Everyting was fine on Monday and since then I cannot send mail. Anyone know if this is a Yahoo problem?

  33. I tried everyting and still cant send mail. Anyone still having send issues? Please help.

  34. Kristina,

    I’m so happy you found this site before you jumped! It is so awkward having to explain what happened when you arrive at the hospital.

    Thank you for you kind words and have a great day!


  35. God bless you! I’ve just found your blog and you saved me from leaping from a one story house!!! lol … I have it working now after hours of tinkering and tears … you are a techie and a fine gentleman!

  36. Abdul Waheed | July 27, 2011 at 1:18 pm |

    Hey!!! its worked….thanks

  37. Andy,

    I’m happy to hear it. Enjoy!


  38. It worked!! Finally! Thanks!!

  39. Dave,

    You seem kind of confused about how all this works. The common types of connection available to tie webmail services like Yahoo and GMX to Outlook are POP3 and IMAP (MAPI is a Microsoft-specific protocol not normally used by third parties). Yahoo supports POP3 for applications like Outlook and IMAP for mobile devices.

    Some people have said that they could get IMAP working with Outlook using the settings for mobile devices, but that it does not make a reliable connection. Others have said that they cannot make the connection work at all.

    Mail services like GMX, which you are using, do officially support an IMAP connection to Outlook which is why you find GMX Outlook 2010 IMAP instructions on this site, but Yahoo does not.

    I hope this clears up the confusion.


  40. WOW!!!! you succesfully setup out look to use POP3 via SSL/TLS – this was not broken . WHat you didndt do was set up outlook to use a MAPI connection ….that is the problem we are having I want to connect with MAPI not POP …. Mapi allows the folder sttructures and mail to have status – Read Not Read etc …. acount using

  41. Hey I HAD the same problem. Be persistent I just went back and fourth with that ssl thing checked then cleared making sure to # Set the โ€œThis server requires an encrypted connection (SSL)โ€ check-box under Incoming server (POP3).
    Then it started working as normal with all settings exactly as described above.
    Hope this helps … BE PERSISTENT !! Take not when I unchecked ssl box incoming reverted back 110 default keep an Eye Out.

  42. I turned SSL back on and am receiving mail. I hope the fix is stable!

    Thanks all.

  43. Diane,

    Give it another shot. I just sent a series of test messages from different accounts and all made it through fine. It looks like they have a fix for this at last!


  44. Diane Reardon | June 25, 2011 at 3:24 am |

    I tried Rhonda’s fix and it didn’t work. Outlook said my username and password weren’t correct. Even logged back into Yahoo to make sure I had it right, which I did, and it wouldn’t work. Tried about 5 times before I gave up. Am really frustrated as I use Outlook to organize my emails, and while I can see them in yahoo, haven’t been able to do anything with them except delete the ones I don’t want.

    Sorry, just letting out some frustration.


  45. 11:20 p.m. EDT After several tweets and emails with Yahoo Customer Care, I arbitrarily did a send/receive in Outlook and 2.5 days worth of emails came flooding in! I didn’t change anything, so evidently they did something on their end. I had to provide them with both account user names. Anyone else?

  46. Thank you everyone for your feedback on how this is working. I think the information will be invaluable to everyone posting here, as well as to all the folks who are just poking their heads in to see what’s going on.

  47. The fix suggested by Rhoda worked for me, but there is a good reason why there was originally security set up for the incoming server. I don’t use yahoo for sensitive info, so the security issue is not very big for me.

  48. The temporary fix described by Rhoda (recent post) doesn’t work for me. After changing the SSL settings, I’m still unable to access my email as of 7:00 p.m. (EDT). It’s now been over 48 hours. They really should send something to our Yahoo mail to let us know what’s going on.

  49. The temporary fix described by Rhoda doesn’t work for me. I still can’t receive my emails; over 48 hours now ๐Ÿ™
