I have just updated to Exchange 2013 CU6 and now facing ActiveSync issue.
Error
Attempting to send the OPTIONS command to the server.
Additional Details
An HTTP 401 Unauthorized response was received from the server. This may be the result of invalid credentials or a configuration problem on the Exchange Server.
