Office 365 - Configuring Other Mail Clients Using IMAP/SMTP
Other email clients are typically not recommended because they do not support Microsoft Exchange and provide only limited Office 365 functionality. Mozilla Thunderbird is the most common example.
You can configure other clients to work with Office 365 by utilizing the IMAP and SMTP protocols instead of Exchange. When setting up an account using IMAP/SMTP, use the account configuration settings listed below when prompted:
Email Address: Your UWM email address (i.e., ePantherID@uwm.edu)
Password: Your ePanther password
Username: Your UWM email address (i.e., ePantherID@uwm.edu)
Incoming Mail Server: outlook.office365.com
Incoming Port Number: 993
Outgoing Mail Server (SMTP): smtp.office365.comOutgoing Port Number: 587
IMAP/SMTP clients will only work for simpler tasks, such as viewing or sending emails. Advanced Office 365 features will need to be accessed using the Outlook desktop clients or Outlook on the web.
