If your preferred email cilent does not support Microsoft Exchange, you can configure it to use the POP or IMAP protocols. However, some features, such as calendaring, will not be available.

Note: ITS strongly recommends Office 365 customers use a mail client that supports two-factor authentication like Outlook or Apple Mail. After <date>, POP/IMAP/SMTP access to Office 365 will not be available from off-campus without a specific exception being granted by the ITS Mail Team. Active users who have used POP/IMAP/SMTP protocols prior to 5/1 will be grandfathered and granted an exception to continue to use POP/IMAP/SMTP protocols, but anyone else will need to request an exception from the ITS Mail Team.

Server Names

Email programs need the name of the server from which they receive messages (POP or IMAP server) and the name of the server that sends messages (SMTP server).

• POP or IMAP name: "outlook.office365.com"
• SMTP name: "smtp.office365.com"

Authentication

To connect using POP or IMAP, you will need to log in with your primary email address and EID password. The outgoing, or SMTP server, should be set to use the same credentials as your incoming server.

IMAP Password Authentication

If you are using the IMAP configuration for Exchange, make sure to use Password authentication only. Other forms of authentication, such as NTLM, MD5, or Kerberos, are not supported.

Ports

Email servers have port numbers for email programs to connect to. The port numbers are standardized, and email programs are defined with these numbers for encrypted and unencrypted connections. SMTP should be configured for TLS security, not SSL.

• IMAP: "993" (SSL required)
• POP: "995" (SSL required)
• SMTP: "587" (TLS required)
