Exchange 2003 stopped serving mobile devices
We are running a Windows Exchange server 2003 SBS 6.5 SP2 which is was working well until recently, when it abruptly stopped serving mobile devices.
There is no problem with outlook clients.
HTTP 500 is returned whenever I try linking the result to our ActiveSync server.
There is nothing weird with the system log every activity is normal. On running the “Exchange ActiveSync with Auto Discover” at https://www.testexchangeconnectivity.com/ an abnormality was detected in the exchange properties as the log File Directory shows:
Access denied: Facility: Win32 ID no: 80070005 Exchange system Manager.
