Hi All,
I have Exchange 2010 (Two CAS) Published by TMG (Basic Authentication). Also outlook anywhere is configured with Basic Authentication.
Some users have issues with "authentication prompt" (randomly). By the way, Outlook Clients(2007/2010/2013) are fully updated.
What I can see when "authentication prompt" shows up, Outlook tries to connect by rpc over https.
Is this a normal behavior?
Regards
Jo
