Greetings,
Our setup: New Exchange 2013 server with an existing 2007 server. Looking to move mailboxes to 2013. When testing with iOS and Android devices we found when composing new messages and using an smtp alias and just typing each users initials (which is a smtp alias of each user plus their regular email address) no results are coming up when connected to Exchange 2013 mailbox on 2013 CAS server. It works when using Exchange 2007 CAS.
If we type the user's first name it comes up with the user and smtp address. However, just typing the 3 letter alias - nothing comes up and we just get "no matches" returned in the messaging app.
I've checked everything I can think of. Ideas or suggestions?
Many thanks!
