Hi!
After deploying Exchnage Server 2013 CU1 with Exchnage 2010SP3 organization I moved 1 mailbox from 2010 to 2013. Outlook gets my data, gets up network connection to server and found parameters successfully. But cant login to server - requests login/password again and again.
Tryed Outlook 2010, tryed other XP SP3 machines - the same issue.
Windows 7/8 - no problem.
Please Help!
