POP, IMAP, and SMTP Clients

As of August 4th, 2020, the POP, IMAP, and SMTP protocols are be disabled for the majority of users.  Access may be granted on a case-by-case basis if there is a demonstrated business need.

Current settings for accessing a Microsoft 365 mailbox via the POP, IMAP, or SMTP protocols is available at POP, IMAP, and SMTP settings for Outlook.com - Microsoft Support.

ActiveSync

ActiveSync is a protocol created by Microsoft that allows mobile devices (such as smartphones, and tablets) to interact with mailboxes in services such as Microsoft 365.

Other ActiveSync applications may not be authorized or supported.  Please note that any ActiveSync clients must support the OAuth 2.0 standard and use multi-factor authentication - other authentication schemes are no longer supported.

Evolution EWS (Linux)

A variant of the Evolution email client for Linux is available which utilizes the Exchange-native Exchange Web Services (EWS) API to access and manage Exchange mailbox content, including Calendar data. For Linux users, this represents the best available option for connecting Office 365 Exchange Online aside from the Outlook Web App.

Installing Evolution EWS

For Ubuntu, Debian, and their variants, open a terminal and run the following shell commands:

sudo apt-get remove evolution sudo apt-get update sudo apt-get install evolution sudo apt-get install evolution-ews

(The first command will remove any existing version in case an older, non-EWS-aware version is present.)

For CentOS or RedHat, open a terminal and run the following shell commands:

sudo yum update sudo yum install evolution sudo yum install evolution-ews

Configuring Evolution EWS to connect to Microsoft 365

Launch the Evolution application. If this is a new installation, follow the prompts below to configure your account. Otherwise, select the menu items File -> New -> Mail Account, click Next, then follow the prompts.

  • Enter your name and your primary SMTP address, uncheck Look up mail server details… and click Next.

  • For Server Type, select Exchange Web Services.

  • For Username, specify your email address.

  • Change Host URL to https://outlook.office365.com/EWS/Exchange.asmx.

  • Click the Fetch URL button, providing your EID password when prompted.  This will result in the OAB URL field being populated, which is the address from which the client can download a copy of the Offline Address Book.

  • Change Authentication to OAuth2 (Office365).

  • Make sure that Override Office365 OAuth2 settings is checked and populate the Tenant ID and Application ID fields as follows:

    • Tenant ID: 31d7e2a5-bdd8-414e-9e97-bea998ebdfe1

    • Application ID: bd4d4c73-8649-4fd0-9c9d-3a88e73432f5

  • Finish the New Mail Account Wizard.

  • You will now be taken to the University’s login page.  When prompted, enter your UT EID (or Microsoft 365 email address) and password and select Sign In, then complete the multi-factor authentication (MFA) requirement if prompted.

Please note that the initial synchronization with your account may take an extended period of time if you have a large mailbox.
