SBS 2008 Active Sync issues

Posted on 2010-11-30
Last Modified: 2012-05-10
We just performed a SBS2003 to SBS2008 migration.  Everything went flawlessly, except for this one issue.  When trying to sync phones to OWA, the connection fails.  I've tried both w/SSL and without SSL....connection fails both ways.  On a regular PC, when trying to access the https://servername/microsoft-server-activesync I'm prompted for UN/PW...after entering credentials, the OWA login page is displayed.  I enter credentials there and am prompted with a HTTP Error 404.0 - Not Found. The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

Detailed Error Information
Module      IIS Web Core
Notification      MapRequestHandler
Handler      StaticFile
Error Code      0x80070002
Requested URL      https://servername:443/owa/default.eas
Physical Path      C:\Program Files\Microsoft\Exchange Server\ClientAccess\owa\default.eas
Logon Method      Basic
Logon User      myuser

When i browse to the physical path on the server, C:\Program Files\Microsoft\Exchange Server\ClientAccess\owa\, the default.eas file is not there.  

How do I recreate the default.eas file?

Exchange and OWA are both up and running, and have not received any negative feedback from the users.  So, all is well there.  Seems as if the migration caused these issues with ActiveSync.  Your help is appreciated!!

The inherited permissions were all unchecked...but after checking them all i still have the issue.  That probably would have been a problem down the road, but it did not resolve this issue.  

It's looking for the default.eas would i obtain/create this file?

default.eas is the Default Activesync Policy - have you configured an Activesync Policy?

Exchange Management Console> Organization Config> Client Access> Exchange Activesync Mailbox Policies> Properties of Default Policy.

Does the Default policy Exist?

The policy that is there is labeled "Windows SBS Mobile Mailbox Policy ServerName"

There isnt one called "default"

when running the exchange connectivity test, below is the output.  We're using a self signed certificate, per the EU's request to save some $$!

Please read the "Limitations of the Self-Signed Certificate" section of the following MS Article:

I always install a 3rd Party SSL cert to make my SBS 08 boxes work and buy them from my GoDaddy Reseller site at or if you prefer -

They are about the cheapest around.

You will need to include the following names: (or whatever you have configured for access)

With a 5 name SAN / UCC certificate - your issues will melt away all for the small cost of $90 (1 year certificate)

Yes - you either need an A record for pointing to the IP Address of your server, or you can add an SRV record, if your Domain Host can create these types of records - some can't.

Sites is used to keep SBS happy - it can often throw up a certificate error if sites is not included.  Don't recall exactly the reason why but read it on a blog site from a Microsoft MVP, so taking it on good authority : )
