MSExchange ActiveSync EventID 1053

In this article we will fix a problem we had with Exchange 2010 when synchronising mail on a mobile device using ActiveSync. When attempting the synchronisation we had the following error message (Source MSExchange ActiveSync, ID 1053) on the CAS server’s eventlog.

Active directory response: 00000005: SecErr: DSID-03151E04, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0
