I am having a problem with my Exchange 5.5 free / busy for one of the users. His calendar cannot be updated when he sends out meeting requests and a person confirms participation. It gives an error: "free/busy could not update your calendar" The same connector is working fine for another user who shares the same secretary. What might be the problem. regards Thomas Kamire DISCLAIMER: This message and any attachments are confidential and may be legally privileged or otherwise protected from disclosure.
