You can connect to Office 365 Exchange Online using the following IMAP settings.  When connecting, your username is not your email address.  It is a derivative of your GT Account, gtaccount@gatech.edu.  (Example:  gburdell3 would use gburdell3@gatech.edu.)  

Service Hostname Encryption Authentication Port
 
Incoming Mail Server (IMAP) outlook.office365.com SSL Required 993
Outgoing Mail Server (SMTP) smtp.office365.com TLS Required 587

Using IMAP to connect to your Office 365 Exchange Online mailbox synchronizes mail only.  Your calendar and contacts can be synced if your email client supports ActiveSync or connecting to an Exchange server.  

Please Note:  In order to use Office 365 as your SMTP server, you must have an Office 365 mailbox.
