An error message may also be logged in the Application event log:
Error: An unexpected, unknown error has occurred.
MAPI or an unspecified service provider.
ID no: 80010106-0000-00000000.
ID no: c1050106 Microsoft CDO for Exchange Management
This problem occurs because CDOEXM cannot initialize COM as multithreaded when the MoveMailbox application programming interface (API) is being called.
