Exchange 2003 HTTP 501 errors, Server ActiveSync

Last Modified: 2012-05-05
The following message keeps popping up on our Exchange 2003 server, stand alone on Windows 2003. The strange part is that the user listed is me, and we do not use ActiveSync for any devices, no push technology, etc. It's a pretty standard Exchange config, with OWA, and everything works fine, just want to troubleshoot and eliminate this error.

Source: Server ActiveSync
Event_ID: 3005

Unexpected Exchange mailbox Server error: Server: [mail.xxx.com] User: [billw@xxx.com] HTTP status code: [501]. Verify that the Exchange mailbox Server is working correctly.
