Hello all,
Well we did the move from Exchange 2007 to Exchange 2013.
But as I wrote this we are facing an issue with authentication. When a user is outside of our office and open Outlook 2010 or 2013 it ask for credentials (Outlook Anywhere), but even he/she enter their username and password it still prompt again and again until we decide to click cancel.
The strange think is even connected to the internal (LAN) we still facing this issue???
Over our Exchange 2013 we configure Outlook anywhere with mail.abc.com internally and externally and we select basic authentication. We already try to use NTLM but things getting worst, user can't open Outlook.
Can anyone provide me step-by-step to resolve this issue, that will be appreciated
Best regards to all of you...
Stephane
