Does Office 365 support POP3 or IMAP?

Yes, Office 365 supports both POP3 and IMAP. Any email client that supports POP/IMAP can also be used.

Configuring POP3 and IMAP (incoming mail)

POP3 and IMAP (from an Exchange mailbox) can only be accessed through a secure connection. Your mail client must support POP3 and IMAP through SSL connections.

  • IMAP server:, port 993, encryption method SSL
  • Incoming POP3 server:, port 995, encryption method SSL

Login using your and password.

Configuring SMTP (outgoing mail)

  • Outgoing SMTP server:, port 587. You will need to authenticate to this server so tick the authentication box. Encryption method STARTTLS or TLS or SSL (It is possible you may find an issue with the encryption method, so please attempt the encryption methods in the order given here until you have one that is successful.)

Login using your and password.

Note: When you POP from Exchange for the first time all mail in the account will be downloaded. It is therefore not advisable to use this method of mail access if you have a large amount of mail in your account.

Looking up email addresses with LDAP

If your mail client has the ability to query an LDAP server, you may also wish to configure it to look up email addresses in the University's LDAP server, the address of which is:

The Base DN to use is: DC=addressbook,DC=local

You will also need to use a bind DN of <username> (replacing <username> with your username)

You must use SSL to encrypt your connection or else authentication will fail.

Information on connecting using POP/IMAP can also be found online at the Microsoft Office 365 support site.
