I am dealing with a user query on this, and I'm not 100% clear on all the ins and outs of resource scheduling. Exchange Server 2007 is used, there's a resource mailbox for a room. The output of Get-MailboxCalendarSetting -identity thismailbox | fl *: AutomateProcessing : AutoAccept AllowConflicts : False BookingWindowInDays : 365 MaximumDurationInMinutes : 1440 AllowRecurringMeetings : True EnforceSchedulingHorizon : True ScheduleOnlyDuringWorkHours : False ConflictPercentageAllowed : 0 MaximumConflictInstances : 0 ForwardRequestsToDelegates : True DeleteAttachments : True DeleteComments : True RemovePrivateProperty : True DeleteSubject : True DisableReminders : True AddOrganizerToSubject : True DeleteNonCalendarItems : True TentativePendingApproval : True EnableResponseDetails : True OrganizerInfo : True ResourceDelegates : {} RequestOutOfPolicy : AllRequestOutOfPolicy : False BookInPolicy : AllBookInPolicy : True RequestInPolicy : AllRequestInPolicy : False AddAdditionalResponse : False AdditionalResponse : RemoveOldMeetingMessages : True AddNewRequestsTentatively : True ProcessExternalMeetingMessages : False DefaultReminderTime : 15 RemoveForwardedMeetingNotifications : False The user is reporting that her entire recurring request is rejected by the resource if one or more non-recurring conflicts exist. She is under the impression that this used to work fine in the past, i.e. the resource would accept all but the conflicting instances. Can someone confirm the expected behaviour in this case?

So there are a couple things that you want to look at for reoccuring meetings. Use the AllowConflicts parameter to specify whether to allow conflicting meeting requests. Use the ConflictPercentageAllowed parameter to set a conflict percentage threshold for recurring meetings. If the percentage of instances of a recurring meeting that conflict with other meetings exceeds this number, the recurring meeting request will be declined. Take a look at this article: http://technet.microsoft.com/en-us/library/aa996340(EXCHG.80).aspx Check out my blogs @ http://cb5.com/blog Chris cbfive.com

Sorry the other setting you want to look at is MaximumConflictInstances. "Use the MaximumConflictInstances parameter to set the maximum number of conflicts allowed for recurring meetings. If the number of instances for a recurring meeting that are in conflict exceeds this number, the recurring meeting request will be declined." Chris cbfive.com

Thanks for the reply. Its not clear from reading the TechNet doc whether AllowConflicts is related to recurring bookings. Do I have to enable it, or would that enable conflicts for non-recurring meetings as well? Can I use either one or both of ConflictPercentageAllowed and MaximumConflictInstances?

This is a good blog http://knicksmith.blogspot.com/2007/05/managing-resource-mailbox-calendars.html. There was a bug on this not sure if it was fixed in SP2 or one of the post roll-ups What you will need to do for these rooms is create an in policy and out of policy. The in-policy will “Accepted” to the recurring meeting. The out-of-policy will reject meetings.
