Hi all,I searched through this forum and also through the KB but couldn't find anything applicable to the exact problem.Our users keep getting this error when trying to create a recurring meeting."Conference Room" declined your meeting because it is recurring. You must book each meeting separately with this resource.We have another conference room that is setup the same way but folks CAN book recurring meetings.Exchange 2007 SP1 Update Rollup 5 Get-MailboxCalendarSettingsworking.room|fl AutomateProcessing:AutoAccept AllowConflicts:False BookingWindowInDays:180 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:True DefaultReminderTime:15 RemoveForwardedMeetingNotifications:False Identity:working.room Get-MailboxCalendarSettingsnotworking.room|fl AutomateProcessing:AutoAccept AllowConflicts:False BookingWindowInDays:180 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:True DefaultReminderTime:15 RemoveForwardedMeetingNotifications:False Identity:notworking.roomThanks,Jon...

Hi Jon, I would like to know whether the not working conference room is moved from Exchange 2003 to Exchange 2007. If I am right, please check whether the AAA (Automatic Auto Accept) or direct booking is enabled on the mailbox originally. Mike

I have this exact same scenario you describe. I just moved mailboxes from Exchange 2003 server to Exchange 2007. Resource mailboxes moved and converted to type Room will not take recurring appointments, even though all options are configured to allow recurring appointments. Anything newly created on Exchange 2007 is able to accept a recurring appointment.We did not have the Auto Accept agent running in the Exchange 2003 environment. I could simply recreate all of the resource mailboxes, given that we do not have a great number of them, but I'd really like to know what the root cause is for future reference. Things like this bug me until I know how they happen...-Furo

I know this is old but I am having the same issue with a couple of my rooms. I moved them from Exchange 2003 to Exchange 2007 and made them a room resource. I made sure before moving them to login to Outlook as the room and go to Tools / Options / Calendar Options / Resource Scheduling and unchecked automatically book. Here is the properties of the room.[PS] C:\Documents and Settings\agiadmin\Desktop>Get-MailboxCalendarSettings MeetingRoom |fl AutomateProcessing : AutoAcceptAllowConflicts : FalseBookingWindowInDays : 180MaximumDurationInMinutes : 1440AllowRecurringMeetings : TrueEnforceSchedulingHorizon : FalseScheduleOnlyDuringWorkHours : FalseConflictPercentageAllowed : 0MaximumConflictInstances : 0ForwardRequestsToDelegates : TrueDeleteAttachments : TrueDeleteComments : FalseRemovePrivateProperty : TrueDeleteSubject : FalseDisableReminders : TrueAddOrganizerToSubject : FalseDeleteNonCalendarItems : TrueTentativePendingApproval : TrueEnableResponseDetails : TrueOrganizerInfo : TrueResourceDelegates : {}RequestOutOfPolicy :AllRequestOutOfPolicy : FalseBookInPolicy :AllBookInPolicy : TrueRequestInPolicy :AllRequestInPolicy : FalseAddAdditionalResponse : TrueAdditionalResponse : You have successfully booked the Seaford Meeting Room (105) for your meetingRemoveOldMeetingMessages : TrueAddNewRequestsTentatively : TrueProcessExternalMeetingMessages : FalseDefaultReminderTime : 15RemoveForwardedMeetingNotifications : TrueIdentity : {AD DOMAIN}/Conference Rooms/Meeting Room (105)I tried this and it worked on one of my other rooms but not the two that I am having trouble with now.Issue: You try to reserve a conference room for a meeting, but get an error - XX Conference Room has declined your meeting because it is recurring. You must book each meeting separately with this resource". But it is a single instance meeting! Cause: If several people have the resource's calendar open and make changes to it at more or less the same time, their client tries to update the Free/Busy info on the server at the same time. This corrupts the free/busy info. (In general, clients should not be making changes directly to a resource's calendar.) Resolution: Change some resource scheduling parameter for the resource from Outlook. For instance, uncheck "Decline conflicting meeting requests". This generates fresh free/busy info for the resource. You can then go back and check it again - the free/busy info will get refreshed yet again.

I found this thread but it took me another hour to figure out how to turn off direct booking settings. For mailboxes migrated from 2003 you probaly used direct booking. You need to remove those settings using Outlook as they are handled differently in 2007/2010. You must log into Outlook 2003 or above using the room as your primary account (not an additional mailbox). You will need permission so use the following command in Exchange Management Shell. Add-MailboxPermission –Identity <Resource-Mailbox> -User <user> -AccessRights <Access Allowed> -InheritanceType <Inheritance’s Type> One you open Outlook, check under TOOLS/OPTIONS/CALENDAR OPTIONS/ button: RESOURCE SCHEDULING remove checkmark from "Automatically accept meeting requestand process cancellations". In 2007 you can change this information via OWA | Options | Resource Settings or via the Set-MailboxCalendarSettings cmdlet
