Hi!
I've got ARR v3 on Windows Server 2012 R2 for external users access to Exchange 2013 (CAS,MBX).
Outlook web application works just fine, but Outlook shows "Connecting" message after entering password.
I'm using just 2 rewrite rules for mail.mydomain.com & autodiscover.mydomain.com.
I can see 401 error in Failed Requests Tracing log, but I'm not sure this is root cause of the problem.
Important notice, because it's a test environment, I'm using laptop with hosts file that contains records pointing to my ARR server external addresses mail.mydomain.com and autodiscover.mydomain.com
Production environment is still working via TMG publishing.
Any ideas how to troubleshoot this issue?
Regards, Alexey
