One of our users is complaining about Calender entries being deleted automatically resulting in missed meetings.

I cheched the MAGT logfile & I can see the following :

[40212] (08/30 02:39:07):{0x13AC} {CN=John Doe/OU=XXX/O=YYY} OTAC reconcile deleting calendar record 68343E347CA6FA55C12571D500229384 (ref -1895008584) (open error 0x4404) for user CN=John Doe/OU=XXX/O=YYY

Can someone tell me what is happening & what is causing the problem?

Thx
