I'm having a hell of a time getting ActiveSync to work.  I was having issues with OutlookAnywhere VDir/etc and reinstalled IIS/CAS.  It fixed all my issues then broke ActiveSync.  The error I get when visiting https://ourserver/Microsoft-Server-ActiveSync is as follows.

Server Error in '/Microsoft-Server-ActiveSync' Application.

===========

I've tried reinstalling CAS Roles again, as well as IIS.  Removing and recreating all VDirs.  Reinstalling .NET 2.0 (as best I could atleast being its built in.. using -u/-i)  nothing seems to change it..  

Any ideas?

Server Exchange 2007 - SP3

Anything in the Exchange setup log file from when you reinstalled CAS?

Not doing anything like redirecting the websites to OWA?

No redirects.  Looks like EWS is giving the same error as well.  This is over and over in the log.

Not sure if this will help, but worth a look:

Open the web.config file located at <Exchange Install folder>\Client Access\exchweb\ews using an editor like Notepad.exe.

2)      Replace all instances of %ExchangeInstallDir% with the actual path of the Exchange installation folder. E.g. If you have installed Exchange in D:\Program Files\Microsoft\Exchange Server replace %ExchangeInstallDir% with D:\Program Files\Microsoft\Exchange Server\.

Here is a line in the web.config file.

Before

<codeBase version="0.0.0.0" href="file:///%ExchangeInstallDir%bin\Microsoft.Exchange.Common.IL.dll"/>

After

<codeBase version="0.0.0.0" href="file:///D:\Program Files\Microsoft\Exchange Server\bin\Microsoft.Exchange.Common.IL.dll"/>

3)      Restart W3SVC service

Is Your AD Toolbox Looking More Like a Toybox?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

That changes the errors into the following:

501 - Header values specify a method that is not implemented.
The page you are looking for cannot be displayed because a header value in the request does not match certain configuration settings on the Web server. For example, a request header might specify a POST to a static file that cannot be posted to, or specify a Transfer-Encoding value that cannot make use of compression.

I believe that is correct when browsing to it - does it now work with a device?

Kind of.  Seems really flakey though. The device wasn't working a second ago.. now it literally just popped up with a message.   I just got a call from a client saying that their mac is now connecting.  So it does indeed look like that resolved it.

I've got a call with Microsoft in an hour.  I'm going to leave this open so I can add notes from that to anyone else who runs into this error.

That's good to hear.

It would seem that changing the installation path doesn't get reflected properly - when you said the errors were present in the install log, combined with the D:\ in your original post, that's what set me thinking.

Glad to have helped.

Worked!

Another way to maybe have solved it would have been to recreate the environment variable for the ExchangeDir
