Question : Odd synch issue with Nokia Mail for Exchange

I have ten users using Mail for Exchange to synchronise their phones with my exchange server.

Eight of them are working perfectly.

The other two receive messages on the phone saying that they do not have permission to sync. The logs show:

 [409]. Verify that the Exchange mailbox Server is working correctly.

Oddly enough both users can browse to http://mailserver/oma and can view that just fine.

Any ideas?

Answer : Odd synch issue with Nokia Mail for Exchange

Okay, I resolved this. Use MfcMapi.exe (available from Microsoft's Downloads) to add a Microsoft-Server-ActiveSync folder to the offending user accounts. Problem solved.
