If you are using a work or school account with Office 365 or other Exchange, before you connect to download mail from another email account, you might need to turn on POP or IMAP access from the other account.

This article provides information about which frequently used email services require you to turn on POP or IMAP access. If you are connecting to an account that is not mentioned here, make sure POP or IMAP access has been turned on BEFORE you try to connect.


To connect to your Gmail account from Outlook on the web, you need to turn on POP access in Gmail settings. You also need to specifically allow Outlook on the web to access your Gmail account.

In Gmail settings, turn on POP Access
  1. Sign in to your Gmail account.
  2. Click the Settings icon and click Settings again from the list

  3. At the top of the Settings page, click Forwarding and POP/IMAP.

  4. Under item 1 Status in the POP Download section, select one of the following two options:
    • Enable POP for all mail (even mail that's already been downloaded)
    • Enable POP for mail that arrives from now on

  5. Click Save Changes.

Outlook on the Web (Office 365)

For instructions on how to do this, please see Connect accounts in Outlook on the Web.

Yahoo! Mail Plus, Comcast, AOL

These services give you POP access automatically and they do NOT support IMAP access.

IMAP Access

Outlook on the web supports IMAP access for most services, except Gmail. With IMAP access, your folders and mail items within those folders are downloaded to Outlook on the web the same way you see them in your other account. If your other account allows IMAP access, make sure that IMAP access is turned on before you connect to the account.
