Effective February 22, 2022, basic authentication will be turned off of Activesync (most mobile devices), IMAP and POP.  We recommend using the Microsoft Outlook mobile app but you can still use the default Mail apps for iOS and Android or your preferred app as long as it supports modern authentication.  However, you must delete your account and re-add it in order to use modern authentication and limited support is provided.

NOTE:  IMAP/POP will no longer be available for new Office 365 users. This is one of the efforts to better secure our email environment.  Please note: If you are currently using IMAP/POP to access your Office 365 account we will not remove access.

However, ITS recommends using Outlook (Windows or Mac) setup as an Office 365 account, OWA or Outlook mobile (iOS or Android) clients instead see Configuring Your Email Client for Office 365 for more information.

We offer limited support for other email clients to access the Office 365 servers.

 

Contact the ITS Help Desk if you have requirements for IMAP or POP access to your account.

IMAP and POP are considered legacy protocols and we recommend using the instructions on the Configuring Your Email Client for Office 365 page to access your Office 365 email. 

 

IMAP - Internet Message Access Protocol (IMAP) works best when you access mail from more than one computer.  IMAP is a way to access email that is kept on a mail server (e.g., Office 365). You manage your mail, mailboxes, and folders on the server, not on your computer.  For example, messages stored on an IMAP server can be accessed from a computer at home, a workstation at the office, or a laptop computer while traveling, without the need to transfer messages or files back and forth between these computers. IMAP eliminates the need to move mail back and forth between the desktop and server.

POP - Post Office Protocol (POP) works best when one has only a single computer, since it was designed to support "offline" message access. Using POP, messages are downloaded to the hard drive and the messages are deleted from the mail server (e.g.,Office 365).  Using your POP email client, you can choose to "Leave mail on the server" and then have access to it from another computer. However, this mode of access is not ideal because it tends to sprinkle messages on each computer you use for mail access. If you use multiple computers, where ALL of them have access to the same server (H:), you can still use POP if you keep your mail on the "shared" drive (e.g., the "H:" drive)
