I have one user that is experiencing the following:
1 - Has a Blackberry syncing with mailbox OTA (via ATT's managed BES)
2 - Uses Microsoft Outlook 2003
3 - Messages get stuck in Outbox (doesn't matter where she composes it; OWA still keeps them in the outbox)
4 - Gets errors (operation failed) when sending calendar messages
5 - Gets "kicked out" of mailbox
5a - Outlook displays "problem accessing your mailbox folders"
5b - Blackberry sync stops working
5c - Can't use OWA - Gets HTTP 503
The following is logged on Exchange's event viewer:
Event Type: Error
Event Source: Server ActiveSync
Event Category: None
Event ID: 3005
Unexpected Exchange mailbox Server error: Server: [exchangeserver] User: [username] HTTP status code: . Verify that the Exchange mailbox Server is working correctly.
How do I get her back in? Simple. I restart the IIS Admin service and she works fine for about another hour or so. Then we repeat the entire process.
I've done the following:
Installed applicable Microsoft updates
Followed Method 2: http://support.microsoft.com/kb/883380
Then I reversed http://chicagotech.net/troubleshooting/activesync3.htm
because no one could sync at that point.
Note: She is the only person experiencing this. No one else.
Thank you for your help.
