Having a weird issue, users who have been migrated to the new Exchange 2013 servers not not able to connect to their mailbox via citrix. They get an error message (SEE PIC)
Odd thing is if this same user logins in to a workstation on the internal Network with either outlook 2010, 2013 it works just fine. My citrix admin assures me its not a citrix issue.
Every users I test internally works no matter the client but once citrix comes into play I get this issue.... Is it some sort or Authentication method maybe Citrix has a problem with or something on the Autodiscover settings?
