We have many users that utilize a vacation calendar, We would like the ability to have as many people schedule time as they need. After 2 or so appointments / meetings get created, the rest get denied as a conflict. I currently have the vacation calendar configured as following... AutomateProcessing : AutoAccept AllowConflicts : True BookingWindowInDays : 365 MaximumDurationInMinutes : 2147483647 AllowRecurringMeetings : True EnforceSchedulingHorizon : False ScheduleOnlyDuringWorkHours : False ConflictPercentageAllowed : 100 MaximumConflictInstances : 100 ForwardRequestsToDelegates : False DeleteAttachments : True DeleteComments : True RemovePrivateProperty : False DeleteSubject : False DisableReminders : True AddOrganizerToSubject : True DeleteNonCalendarItems : True TentativePendingApproval : False EnableResponseDetails : False OrganizerInfo : True ResourceDelegates : {} RequestOutOfPolicy : AllRequestOutOfPolicy : False BookInPolicy : AllBookInPolicy : True RequestInPolicy : AllRequestInPolicy : False AddAdditionalResponse : False AdditionalResponse : <DIV><FONT face=Tahoma size=2></FONT></DI V> RemoveOldMeetingMessages : True AddNewRequestsTentatively : True ProcessExternalMeetingMessages : False DefaultReminderTime : 15 RemoveForwardedMeetingNotifications : False Identity : Domain.com/Exchange/Resource Mailboxes/ IT Vacation Calendar

That is the default behaviour. since the below is true. AutomateProcessing : AutoAccept Before booking users needs to check the schedule of calendar in order to avoid conflict. Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

We want to allow as many conflicts as possible.

tat present it is set as below MaximumConflictInstances : 100 But you can change it as below Set-MailboxCalendarSettings -identity confroom -maximumconflictinstances:1000 Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Hi, According to following article, the MaximumConflictInstances parameter is used to control the maximum number of conflicts for recurring meeting. For single meeting, I think that the MaximumConflictInstances parameter is not helpful. Set-MailboxCalendarSettings http://technet.microsoft.com/en-us/library/aa996340.aspx ConflictPercentageAllowed: 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. 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. My following thread describes the two parameters more detailed: http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/3cd4f5c2-7a63-4d76-a100-18505f0c9e10 Therefore, would you please let me know whether you would like to configure Resource Mailbox to accept Recurring Meeting with as many conflicts as possible? Or you would like to accept Single Meeting with as many conflicts as possbile. Mike

I would like to allow reoccurring and non reoccurring meetings with as many conflicts as possible.

You will have to set the ConflictPercentageAllowed and MaximumConflictInstances: The command would be same as we did earlier Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Hi LKeneston, I would like to explain that we do not have a method to configure the Resource Mailbox to accept the first two conflict single occurrence meeting and reject the third conflict meeting. We either reject all conflict meetings or accept all meetings by setting AllowConflicts parameter to True. Hi Vindod, As I explained in previous thread, the ConflictPercentageAllowed and MaximumConflictInstances parameters are used of Recurring meeting. For example, I have a Resource Room mailbox configured like below: AllowConflicts: False ConflictPercentageAllowed: 80 MaximumConflictInstances: 5 If the resource mailbox received a recurring meeting request which has 8 instances (4 instances are conflict with exist calendar items in the resource mailbox), the Resource Assistance will first check ConflictPercentageAllowed parameter, as only 50% instances are conflict, the Meeting request pass the check. Then, the Resource Assistance will check the MaximumConflictInstances parameter, as only 4 instances are conflict, the meeting request will pass the check. Then, the Resource Assistance will send email to organizer to accept the reoccurring appointment for the times it is available and reject for the times it isn't. If the ConflictPercentageAllowed and MaximumConflictInstances parameters are set to 0, in the above example, the entire meeting will be rejected. Nevertheless, based on my test, the two parameters are not helpful for single occurrence meeting. Mike

You will have to set the ConflictPercentageAllowed and MaximumConflictInstances: The command would be same as we did earlier Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3| Set them to what? they are both set to 100 now, i believe that is the max.

I do not want it to reject any meetings, reoccurring or not.

Hi LKeneston, Sorry for delay in response. For some reason, I do not receive alert for the post. After reviewing the entire post again, I guess that I may misunderstand your current situation and requirement previously. Whether you would like to accept all meeting request to the resource mailbox? Nevertheless, currently, after two appointments are created, the rest appointment is denied due to conflict. You would like to fix the issue. If I am off base, please let me know. I have created a resource mailbox on my lab with configuration like below. I am able to book over three conflicts meeting (Single instance meeting) in the resource mailbox. Nevertheless, if I attempt to book a recurring meeting (Multiple instances), the conflicts instances will be rejected while the entire meeting is accepted. I have performed some researches regarding the issue. Nevertheless, I do not find any options to configure to accept the conflicts instances. AutomateProcessing : AutoAccept AllowConflicts : True 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 : <DIV><FONT face=Tahoma size=2></FONT></DI V> RemoveOldMeetingMessages : True AddNewRequestsTentatively : True ProcessExternalMeetingMessages : False DefaultReminderTime : 15 RemoveForwardedMeetingNotifications : False Identity : lab.com/Users/room Therefore, I suggest you create a new test resource mailbox and configure the resource mailbox to auto-accept meeting request and allow conflicts. Then, please check whether over three conflicts meeting (Single Instance) can be accepted.

Hi LKeneston, In addition, I also suggest you consider using Direct Booking instead of Resource Booking. Based on my local test, the direct booking is able to achieve your requirement: To enable direct booking on a mailbox: Outlook Tools | Options | Calendar Options | Resource Scheduling Select Automatically accept meeting requests and process cancellations and do not select the other two options. How to direct book a resource in Outlook http://support.microsoft.com/kb/291616/en-us You can refer to following article to know the advantage and disadvantage of direct booking: Resource scheduling in Exchange Server 2007 http://msexchangeteam.com/archive/2007/05/14/438944.aspx Exchange 2003 Auto Accept Agent vs. direct booking http://msexchangeteam.com/archive/2006/02/22/420275.aspx Thanks, Mike

Hi LKeneston,Any updates regarding the issue?Mike

This seemed to have worked except when a meeting is canceled it is marked as such on the vacation calendar. Any way to have the resource mailbox delete it upon cancel?
