Adding POP or IMAP accounts to Office 365 Users


 

If you use Office 365 or other Microsoft Exchange-based email, you can add an email account from another email service (for example, Gmail, Yahoo! Mail Plus, or Comcast) as a connected account. For information about how to add a connection to another email account, see Connect to another email account.

In most cases, you an add the connected account by typing your email address and password. However, if the settings for the account you want to connect to can't be detected automatically, you'll be prompted to enter POP or IMAP server information for that account. You may also need to enter the server information if you've already connected to the account but the connection isn't working.

Tip    Some email services require that you make an account settings change on the other service before you can connect to your other email account using another service. For example, before you can successfully add a connection to Gmail account, you must log in to your Gmail account and enable POP connections. For more information, see Turn on POP or IMAP access to connect to another account.

Do I choose POP or IMAP?

The table below lists some email providers that are used frequently, and whether you should use POP or IMAP when connecting to another account. If your provider isn’t listed, check with them.

For example, if you’re connecting to a Gmail, Yahoo! Mail Plus, Comcast, or AT&T Worldnet (high speed) account, connect to your account using POP. For directions, skip to the POP section in this article.

If you’re connecting to AOL, we recommend that you use IMAP because it offers more features.
