world, your end users can’t live without their smartphones. If they cannot get to email from anywhere at any time, deals exchange activesync authentication failed could fall through and that just can’t happen. Ensuring that Exchange ActiveSync is working properly on both your Exchange infrastructure and your users’ myriad mobile devices is one of the most important things you can https://support.microsoft.com/en-us/kb/2469722 do. Usually, EAS works perfectly well, so this is not a problem for you. But occasionally, things do fail, so knowing what to look at and how to troubleshoot are critical skills. This article should help get you started. Basics Make sure DNS is properly resolving the autdiscover.example.com name, that the user is attempting to use valid credentials that aren’t locked out, and that the certificate on the CAS server http://www.gfi.com/blog/how-to-troubleshoot-exchange-activesync-connections/ has not expired. It is amazing how many times sysadmins let a certificate expire, so don’t overlook that!

Troubleshooting Exchange ActiveSync and reading IIS logs In this article I will try cover my way of troubleshooting Exchange ActiveSync issues from Server side and client side. Recently I had an issue where users on one of the Exchange http://msexchangeguru.com/2012/02/01/exchange-activesync/ 2007 servers "ONLY" weren't able to sync their mobile device. My way of troubleshooting flows this way which I will explain in detail: Isolate the issue be for user, device, server or organization wide Testexchangeconnectivity.com and a test mobile device Read IIS logs and look at the error's if any Confirm Authentication settings on IIS VDir's for CAS and MBX roles Look at CPU utilization for w3wp.exe on all CAS servers Read event activesync error logs and filter MSExchange ActiveSync event in 10xx series Confirm ADPermission for internet facing CAS servers on "ms-Exch-EPI-Token-Serialization" Isolate the issue be for user, device, server or organization wide This is the primary focus area or we will be going in circles. Let's split this into 4 different scenario and the issue should be isolated to one of these: Issue with one single user only: First thing I would look for is exchange activesync error to check the OMA AD property enabled or not. Navigate to Active Directory Users and Computers à Search for the user à Exchange Feature tab à Ideally, if this all set to enable, the attribute "msexchOMAAdminWirelessEnable"will be
