I have a user that sent a meeting request to a room resource and put the wrong date on it. It is no longer on her calendar and it is not on the Room Resource Calendar either. The problem is that she gets emails from the room resource saying "Could not process your reservation" and in the body it has "You cannot book a conference in the past." How do I get this to stop? Thanks in advance. I am running Exchange Server 2007 and Outlook 2007.

Hi, Do you mean that the user keeps getting the message "Could not process your reservation"? Please check if the settings of room resource are correct: 1. Log into room resource's mailbox by using OWA. 2. Click Option, Resource Settings, please see if the following options are checked: Automatically process meeting request and cancelation Disable Reminders And see if Allow conflicts box is unchecked. If the issue persists, please help me to the collect the calendar settings of this room mailbox for further research: 1. Open Exchange Management shell, type: Get-mailboxcalendarsettings roomAlias |export-csv c:\settings.csv 2. locate the file settings.csv and upload this file to your skydrive.

Here is the link to the settings.csv settings.csv

Hi, Thank you for uploading the information. I have checked these settings and found that the parameter 'AllRequestOutOfPolicy' was set to true. This causes your problem. Please set this 'AllRequestOutOfPolicy' to false and see if the issue persists: Open exchange management shell, type: Set-mailboxcalendarsettings roomAlias -AllRequestOutOfPolicy:$false
