Hi,
Requests for appointmentsto take place in 30 minutes are automatically rejected for our resource mailboxes in Exchange Server 2010,We received the answer that the appoinment was rejected because it was set in the past butif we request for an appointmet to take place beyond 31 minutes, there is no problem.
Time in all computers are synchronized as showed below. Our Server Admin had to untick the option "Automatically adjust clock...." because we couldn't get the right time in servers after DST Change
- There are no error messages in event viewer for Exchange server nor DCs. Clients neither.
- Time providers policies have been enabled in GPO (NTP Client is "time.windows.com,0x9")
Some help will be much appreciated.
