Exchange ActivSync - SBS2003

Hi!

My client has a MS SBS2003 SP2 Standard server.  It's primary function is file/print, email, sharepoint and a 3rd party d/b running.  Randomly, clients lose their MS Outlook connections to the server.  When they do, it is filled with an error message similar to the following:

Event Source: Server ActiveSync
Event ID: 3005
Description: Unexpected Exchange mailbox Server error: Server: [Internal Domain name] User: [Email address of the user] HTTP status code: [501]. Verify that the Exchange mailbox Server is working correctly

A short fix is to reboot the server, all services come up normal.  I've also reviewed this article from MS and found all permissions are ok.  http://support.microsoft.com/kb/937635

Thoughts?  TIA!

Steve

Please have a read of my Exchange 2003 / Activesync Article which has the correct settings for IIS together with tests / fixes for various errors:
http://www.experts-exchange.com/articles/Software/Server_Software/Email_Servers/Exchange/Exchange-2003-Activesync-Connection-Problems-FAQ.html
The https://testexchangeconnectivity.com site should produce a more useful report.  Use the Exchange Activesync Test specifying manual server settings.

I assume they Outlook is configured as RPC/HTTP?
Are they using Outlook 2003/2007?
Is the problem happening when they are internal to the network or external or both?
Hope this helps, If I've missunderstond your question please elaborate.

@ConchCrawl - This is an activesync question - Not HTTP over RPC.  I think you might be getting the two confused?

ConchCrawlCommented:
I have to disagree somewhat :-) that since he indicated that this was an outlook issue and not an iPhone issue (or other pda) I had to assume he was using rpc/http for outlook and for activesync to work properly then rpc/http has to be working properly.
Maybe I'm wrong, which is possible, but that has always been my understanding of how things work.
So I'm not sure where exactly his problem exists at this point, so please clarify if I'm missing something.

@conchcrawl - I can see where you are going based on the Outlook connections dropping randomly comment.
The Question is Exchange Activesync - SBS2003, the error is Server Activesync 3005 and the KB linked to is an Activesync article, hence my Activesync response and my question to you, but I guess time will tell.  You may well be right : )
@sdeblock - Can you explain a little more about the problem please.

To clarify, the entire setup is rpc/https, self sign.  At random points at night (not every night), all exchange connectivity drops and this log error appears.  Windows PDA's, MSO 2007 both do not work (there are no other PDA's).

Event Source: Server ActiveSync

What Anti-Virus software have you got installed on the Exchange server?  Anything that came in a yellow box by any chance?
0
sdeblockAuthor Commented:
AV is Panda for server protection and SAVMSE 5.05 for the exchange protection.

Alan HardistyCo-OwnerCommented:
Have you got the following registry key setup on the server?
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\VirusScan
ProActiveScanning=1

sdeblockAuthor Commented:
Yes, that registrykey exists.

Two thoughts - remove the Panda Antivirus and monitor for a day or so - see if thigs improve.
Second thought - remove Symantec Mail Security - it caused my servers I managed no end of problems and I eventually replaced it with a different product (Vamsoft ORF).
Now - I am trouble free.
You can always put the Panda and Mail Security back on if no progress is made. Symantec Allows you to export your setting to an .XML file so that you can restore the settings later.
Vamsoft allow you to trial their software in case you are interested.  Also, it only costs $239 per server.

Thanks for your input Alan, I've compared a multitude of Exchange exclusions from at least 20 different legit posts up against mine.  I've made some further changes to the Panda File Exclusions that I thought may impact the Exchange Sync.  I guess at this point only time will tell.

This is why I never, anymore, install AP on a server especially SBS, they have so many exclusions it's almost impossible from an administrative function to keep up with it. I install the agent only to run scans in the evening and not active protection. This hasn't caused any problems, but the other has on more than one occassion caused me a headache:-).
Hope this helps.

I found the issue finally - memory management wasn't originally setup correctly (do not use windows /3gb switch)  Further, had to do an offline defrag of the Exchange Database which freed up 8gb.  This was important because nightly they were teetering on their d/b size limitation which tripped up exchange.  The pure volume of email which they receive kept hitting the exch d/b size limitations (which had been changed 4 times previously).

Thanks for your suggestions!
