I have recently migrate my Exchange server from exchange 2007 to Exchange 2013 and AD 2003 to 2012. I am using my display name like MHT (Md. Mahatab Hossain) where MHT is my login name. If i search any address from outlook using MHT (Login name) then i can easily find out. But in my mobile i have to write email address like mahatab.hossain@example.com then i find out.
In exchange 2007 i was able find out address using MHT (Login name) in my mobile.
Please help me on this.
