UAB IT to stop supporting legacy email protocols

Next month, UAB IT will stop supporting legacy email protocols such as IMAP, POP3 and SMTP.

This is not a change that will affect most email users on campus.

Beginning Oct. 12, UAB IT will begin provisioning all new user accounts without legacy protocol support for accessing the user’s Office 365 UAB.EDU email account; these protocols include Exchange ActiveSync (EAS), Messaging Application Programming Interface (MAPI), Exchange Web Services (EWS)
Internet Message Access Protocol (IMAP), Post office Protocol version 3 (POP3), and Simple Mail Transfer Protocol (SMTP).

Beginning Oct. 19, UAB IT will cease supporting any connections for existing UAB.EDU user addresses using the IMAPPOP3, and SMTP legacy protocols.

While most modern mail clientswill continue to function, we recommend that users connect to their UAB Office 365 email through one of the following ways:

  • Via the Outlook 2013 (or later) desktop client
  • Using the most current version of Outlook App for iOS/Android
  • By connecting to Outlook on the Web ( using a supported web browser

Users who determine that they have a business need for using a legacy protocol should contact AskIT and request a security exception. Please note, this change does not affect appliances (such as printers) sending via SMTP; this is for Office 365 UAB.EDU user email accounts only.

Since Jan. 8, 2018, Duo Two-Factor Authentication (2FA) has been available as an optional protection mechanism for UAB users. Disabling legacy mail protocols is required to ensure that malicious actors cannot bypass 2FA by using a legacy protocol that is not compatible with 2FA.

If you have not signed up for 2-factor authentication, we encourage you to do so at to better protect your accounts and UAB data. As an incentive, if you use 2FA, you never have to change your BlazerID password again (unless the account is compromised).

If you have any questions, please contact AskIT or 205-996-5555.
