hamdy916 0 Report post Posted January 23, 2014 Hi, I have a problem with accessing OWA from a CAS server. This is my setup Site A - Ex1 (CAS,Hub,mbx) Site B - Ex2 (CAS,Hub,mbx) If user1 mailbox is on EX1, if I access OWA from EX1 everything works fine. If I access user1 mailbox from Ex2, I get the following error. Outlook Web Access is not available. If the problem continues, contact technical support for your organization and tell them the following: There is no Microsoft Exchange Client Access server that has the necessary configuration in the Active Directory site where the mailbox is stored.
