Hello, I use Exchange 2007 and created a room. When a user sets a room the person invited is able to change the subject's appointment. Would you know how to avoid that change? Only the organizer should set and be able to modify the subject line. I have copied the room configuration: get-mailbox -identity ROOM3 | fl and get-mailboxcalendarSetting -identity ROOM3 | fl UseDatabaseRetentionDefaults TRUE RetainDeletedItemsUntilBackup FALSE DeliverToMailboxAndForward FALSE RetentionHoldEnabled FALSE ExchangeUserAccountControl AccountDisabled ExternalOofOptions External IsMailboxEnabled TRUE IsResource TRUE IsLinked FALSE IsShared FALSE LinkedMasterAccount AUTORITE NT\SELF ResourceCustom {} ResourceType Room SamAccountName ROOM03 AntispamBypassEnabled FALSE UseDatabaseQuotaDefaults TRUE IssueWarningQuota unlimited RulesQuota 64KB UserPrincipalName ROOM03@company.com UMEnabled FALSE Alias ROOM03 DisplayName ROOM03-DISPLAY EmailAddresses {smtp:ROOM03@company.intra, SMTP:ROOM03@company.com} GrantSendOnBehalfTo {GRAIG, TOM} HiddenFromAddressListsEnabled FALSE MaxSendSize unlimited MaxReceiveSize unlimited PoliciesExcluded {} EmailAddressPolicyEnabled TRUE PrimarySmtpAddress ROOM03@company.com RecipientType UserMailbox RecipientTypeDetails RoomMailbox RejectMessagesFrom {} RejectMessagesFromDLMembers {} RequireSenderAuthenticationEnabled FALSE UMDtmfMap {} WindowsEmailAddress ROOM03@company.com IsValid TRUE Name ROOM03 AutomateProcessing AutoAccept AllowConflicts TRUE BookingWindowInDays 180 MaximumDurationInMinutes 1440 AllowRecurringMeetings TRUE EnforceSchedulingHorizon TRUE ScheduleOnlyDuringWorkHours FALSE ConflictPercentageAllowed 100 MaximumConflictInstances 100 ForwardRequestsToDelegates TRUE DeleteAttachments TRUE DeleteComments TRUE RemovePrivateProperty TRUE DeleteSubject FALSE DisableReminders TRUE AddOrganizerToSubject TRUE DeleteNonCalendarItems TRUE TentativePendingApproval TRUE EnableResponseDetails TRUE OrganizerInfo TRUE ResourceDelegates {GRAIG, TOM} RequestOutOfPolicy {GRAIG, TOM} AllRequestOutOfPolicy FALSE BookInPolicy {GRAIG, TOM} AllBookInPolicy FALSE RequestInPolicy {GRAIG, TOM} AllRequestInPolicy FALSE AddAdditionalResponse FALSE AdditionalResponse <DIV><FONT size=2 face=Tahoma></FONT></DIV> RemoveOldMeetingMessages TRUE AddNewRequestsTentatively TRUE ProcessExternalMeetingMessages FALSE DefaultReminderTime 15 RemoveForwardedMeetingNotifications FALSE Thanks in advance for your help.

Can you check the permissions on the calendar of the room and see what's listed?James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi Try to use Get-MailboxPermission -identity ROOM3 | FL See if there is any permission issue CheersZi Feng TechNet Community Support

Hello James, I checked the calendar permissions but don't find an option that would disable to change subject. Maybe as the users have "Editor" permission level it allows them to do so..? Any thing I could do? find below a SS of the calendar permission of the room Many thanks, Graig

Hi Another question is, when the user change the Subject, did it affact other users' subject? The person who got invited cound change Subject and Time on his owa calendar, but it will not affect others. Please have a confirm CheersZi Feng TechNet Community Support
