Hello Hope this is the right forum for my question. To start with I know that the resource setup isn't optimal as this was able to happen, but what's happened, that's happened :/ Two of our users were able to reserve the same resource and each of them insists to have been first. It may be so or not ;) but it is very difficult to go and say, unless there are some facts and neither of them is ready to yield (the resource is for personal, not company use [a cottage]). Now the simple question is: can I found out when did each of them make the booking? Please bear me if this is something every Exchange admin should know (I am not one - rather a developer) TIA Hank

Hi, I am not sure of how to found the past event. But in future you may add the performance counter: MSExchange Resource Booking\Average ResourceBooking Processing Time to track as your requirement Regards from www.windowsadmin.info

Thank you..but I am still looking for possible answer from the past :) We must set the resource not to even allow double bookings in the futuru on this resource... hank

To avoid conflict resource booking, you can type the following cmdlet: Set-CalendarProcessing -Identity "Conference" -AutomateProcessing AutoAccept -AllowConflicts $false For more information, please refer to the following article: http://technet.microsoft.com/en-us/library/dd335046(EXCHG.140).aspx Thanks.

Thank you Novak I just should have found out after-the-fact what has happened and in what order. We will do this to avoid similar problems in the future, but the harm is already done and it makes things a bit tough. brg, hank
