Hello,
I'm in the middle of a transition from SBS 2011 to 2012 R2. Currently Exchange 2010 and 2013 co-exists. Every time I start Outlook (2013) it asks for credentials. If I use user@domain.local format it does not accept. If I use domain\user format, I
have to enter it 2 or 3 times, then Outlook works fine.
OWA, AS, mail flow seems to be working.
What can cause the password prompt?
TIA
