Title
Error: "Can’t get working hours, object that is unlicensed or never logon may cause this issue" -
Description
Exchange FreeBusy requests to new created rooms fail. -
Cause
Coexistence Manager for Notes (CMN) and Coexistence Manager for GroupWise (CMG) both uses Microsoft EWS API to retrieve F/B and working hours information. The API will return the working hours as NULL when the object's working hours has not been set. This is an EWS API limitation. -
Resolution
CMN/CMG call "ExchangeService.GetUserAvailability()" which returns "GetUserAvailabilityResults", and "GetUserAvailabilityResults.AttendeesAvailability.WorkingHours" is what CMN takes as workinghours, which is null when the object is not manually set.
WORKAROUND 1:
Unchecking CMN/CMG option "Show Work Hours" should fix this issue:
WORKAROUND 2:Set working hours manually running below cmdlets:
Set-MailboxCalendarConfiguration -Identity Tyler -WorkingHoursTimeZone "Pacific Standard Time" -WorkingHoursStartTime 08:00:00 -WorkingHoursEndTime 17:00:00
Set-MailboxRegionalConfiguration -Identity Tyler -TimeZone "Eastern Standard Time" -Language en-US -DateFormat "M/d/yyyy"
