Exchange ActiveSync/Outlook Anywhere Connectivity Issues

Over the last several years I’ve come across all sorts of issues connecting mobile phones to Exchange servers for syncing purposes… These have ranged in fixes for Exchange 2003 and needing to create an exchange-oma virtual directory, with some registry key changes, to fixing security problems within AD to resolve the issues.

In the past 6 months or so, I’ve been using this site to test these configurations (it saves messing around with your phone, or Windows Phone simulators):

This is the Exchange Remote Connectivity Analyser, and it works miracles!

It’ll test Autodiscover for you… as well as then trying to sync (with the account details you provide) with your mailbox (change the password before and after!). It then gives detailed steps and error messages (as well as links pointing to the usual causes of the problem) which can be used to troubleshoot further.

Sometimes it’ll complain about public certificates (usually if there is an intermediate CA in the certificate path), but if this is the case, just tick the “Ignore SSL Errors” check box, and it’ll happily run the test and only give you a warning instead of an error.

This site has helped me so many times before, and is extremely useful for troubleshooting… I always make this my first port of call should I have any Outlook Anywhere/ActiveSync errors.

I hope you find it as useful as I do!
