Outlook is using GUID not Server name

Technical issues in exchange 2013 that we must know

Outlook is using GUID not Server name

Outlook clients no longer connect to a server FQDN as they have done in all previous versions of Exchange. Outlook uses Autodiscover to create a new connection point comprised of mailbox GUID, @ symbol, and the domain portion of the user’s primary SMTP address.

Ex: MailboxGuid @ SMTP Domain (DomainName)

This change has helped to get rid of the message “Your administrator has made a change to your mailbox. Please restart

 It is used in conjunction with AutoDiscover to allow seemless moves of servers for future and current (if you’re moving mailboxes and the like)
