ActiveSync Error - 0x8600010b - Could Not Syncronize [unknown] Dustin Humm 06-15-2006

We have Small Business Server 2003 Premium SP1 with Exchange 2003. We are
having difficulty synchronizing mobile devices (multiple smartphones and
PDAs) with Exchange. Each time we try to sync, it connects, authenticates
and downloads the folder hierarchy within the user's Outlook/Exchange
mailbox. It then 'crashes' and gives us the error message listed in the
subject of this post.

We have not gotten this to succeed at any point on any device.

We are using SSL, have generated our own cert and have either a) downloaded
both the root cert as well as the server cert to the WM 5.0 mobile devices or
b) Used DisableCertChk to disable SSL cert checking on earlier PPC devices...

We have verified that OWA, OMA & all web/SSL components are working just
fine - perfectly, in fact. Additionally, I have already resolved many of the
common errors with Activesync regarding SSL certs, Basic/NTLM authentication,
Forms Authentication, Exchange-OMA virtual directories & ISA FW traffic
blocking. I have searched MSDN, Google & the MS KB for any indication of
this particular error and cannot find ANY articles that address this specific
code.

Also, in looking at the Activesync log, one direct question I do have is,
'what are the XML status codes?' In other words, the very last line in the
log below states <STATUS>8</STATUS>. What are the various status codes that
can be returned? And, furthermore, are these codes relative to XML more than
they are to any particular Activesync operation? I have been unable to find
further info on these codes either...it may help me find the direction of our
next step...

What I "see" happening during the sync process is as follows:

1) Mobile device hits the Internet using SSL
2) Mobile device attempts to connect to our Exchange server
3) ISA accepts & allows the client request
4) Mobile device connects to our server
5) IIS accepts the request and 'passes it' to Active Directory for
authentication
6) User is successfully authenticated
7) Mobile device issues PROPFIND, etc. commands
8) Server responds with 200 OK and continues the connection
9) Mobile device issues a GET HIERARCHY command
10) Server responds with the user's inbox hierarchy (successfully)
11) Mobile device issues the SYNC command
12) Server responds with 200 OK & (XML?) status code 8 (failed?)
13) Mobile device displays the 'Could not synchronize [unknown]' error with
a status code of 0x8600010b

As I mentioned, I also tried this with older devices using PPC
2002/2003...same result, but the error code is different - 0x80004005 -
Synchronization failed. Try again...etc.

I have included sample log file output in this post for your review.

Any help wold be greatly appreciated as I am quickly running out of ideas...

Thanx!!

Dustin.
