The Cablevision Outlook 2010 Connection

Cablevision Outlook 2010 – Make a Cablevision Optimum Online to Outlook 2010 Connection

Would you like to save yourself some time and effort by making your Cablevision Optimum Online email available in Outlook 2010? If so, you’ve come to the right place.

On this page, we’ll walk through all the steps necessary to make this connection. But first, we should touch on a few points.

First, Cablevision doesn’t allow you to send mail across their network if you aren’t physically connected to it. For example, if you are using a laptop while you are on the road, you will find that you can’t send mail through the Cablevision network.

But there’s a way around this problem. Cablevision suggests that you use a different SMTP server to send your messages, one that isn’t limited by Cablevision.

If you plan on using your Cablevision Outlook connection on the road, you should first configure your Cablevision Outlook 2010 connection at home, using the instructions on this page.

Once you have that working properly, you should follow the link at the bottom of this page to SMTP2Go, where you can sign up for an SMTP service that works anywhere in the world, without any restrictions.

Second, setting up this connection deletes your Cablevision Optimum Online mail from the Cablevision web mailbox once Outlook 2010 downloads it. That means you won’t be able to read your Cablevision mail using your web browser after you set up this connection. That may sound like a drawback, but it really isn’t.

Because of the technology Cablevision uses for its email, there’s no way to keep your Outlook 2010 and your Cablevision web mailbox synchronized. If the mail wasn’t removed from your web mailbox, you would end up with two independent copies of each message, one in Outlook and one in your web mailbox.

Suppose this morning you read a message from me in your web mailbox, and replied to it. The next time you started Outlook, you would see that message again in Outlook, and would have to remember whether you had already dealt with it. It is a recipe for major confusion. That’s why messages are removed from the web mailbox once Outlook downloads a copy of them.

Third, please be aware that I am not a Cablevision Optimum Online user. These instructions are based on Cablevision Outlook connection information published by Cablevision for earlier versions of Outlook. I have simply adapted them for Outlook 2010. They should work perfectly well, but if you find any issues, please email me and let me know so we can get the problem resolved.

How to Make the Cablevision Outlook 2010 Connection

Follow these steps to get your Cablevision email in Outlook 2010:

  1. In Outlook 2010, click the File tab on the Ribbon. In the “File” menu that appears, click Info to display the “Account Information” screen shown below.

  2. Cablevision Outlook 2010

  3. Click Add Account to open the “Add New Account” page of the “Auto Account Setup” wizard.
  4. Optimum Online Outlook 2010

  5. Select the Manually configure server settings or additional server types option, then click Next. There is no need to enter any other information on this screen as we will be entering it on the next one.
  6. On the “Choose Service” screen that appears, select Internet E-mail, then click Next. This opens the “Internet E-mail Settings” screen.

  8. In the “User Information” section of the screen, enter your Name as you want it to appear in messages.
  9. Enter your full Comcast Optimum Online E-mail Address.
  10. In the “Server Information” section of the screen, select POP3 as the “Account Type.”
  11. For “Incoming Mail Server” and “Outgoing Mail Server (SMTP),” enter
  12. Enter your Comcast Optimum Online user name in the “User Name” field.
  13. Enter your Comcast Optimum Online password into the Password and Retype Password fields, and set the Remember Password option so you don’t have to manually enter the password every time Outlook wants to check for new mail.
  14. Confirm that the Require logon using Secure Password Authentication (SPA) option is NOT selected.
  15. Click the Test Account Settings button to confirm that your Comcast Optimum Online Outlook 2010 connection is set up properly. After a moment or two, you should see a box with the message, “Congratulations! All tests completed successfully.” This tells you that all is well. Click Close to close this box and return to the “Internet E-mail Settings” screen.
  16. Click Next, then Finish.

That was the last step. Your Comcast Outlook 2010 connection should now be up and ready to go.

NOTE: If the test shows that you can receive messages fine, but you can’t them, the problem is often caused by factors outside the Cablevision Outlook 2010 connection you just set up. I’ve posted instructions for troubleshooting that kind of problem on the Can’t Send Email page.

Going to Be Using this Connection While Traveling?

As I mentioned earlier, Cablevision suggests that you use a third-party SMTP server when you are on the road. If you don’t, you won’t be able to send mail.

The service I recommend is called SMTP2Go. It is a proven worldwide solution that I’ve been recommending for years without issue. The service is incredibly inexpensive (as low as $1.99/month) and they provide a 7-day free trial (no credit card required) so you can give it a good test before making a commitment.

If you want to take your Cablevision Outlook connection on the road, I think SMTP2Go is the way to get it done.
