I've got a client, who is using a Verizon mobile phone running Windows Mobile 6 on it. We set it up so that he could connect to the Exchange Server over the air. The server is a Windows 2003 SBS machine running Exchange 2003.
Everything was working perfectly. Until he decided he wanted to back up his files onto his PC. So when he connected the PC USB Cable, he set up a second sync source (the PC).
Now when he tries to ActiveSync over the air, we get an error code: 0x85010014
We tried deleting both sync sources and recreating the Exchange sync, but it didn't fix the problem.
We took it down to Verizon and tried a hard reset of the phone, but again it didn't fix the problem. Verizon even tried configuring some brand new phones, but it didn't work, so they are saying the problem is on our end. But our end WAS working, so I don't really think it's a problem with the Exchange Server.
Anyone got any ideas? It's really frustrating him.
