When a Exchange 2007 user forwards a meeting request to someone, the meeting organizer will get a Notification with subject “Meeting Forward Notification: [actual meeting subject]” saying that meeting request is forwarded to people listed in notification email body. Though Microsoft says that it is a new feature, many of the users felt it annoying. In this article I am going to talk about how to disable this behavior.
To disable this functionality for a single mailbox, use the below cmdlet
Get-MailboxCalendarSettings -Identity user1 | Set-MailboxCalendarSettings -RemoveForwardedMeetingNotifications $true
Note: You can not really disable this behavior(or I haven’t come across any such procedure), but by applying above procedure, you are making meeting request forward notification messages to go directly into “Deleted Items”. This way users won’t get annoyed with these notification messages. Alternately, you can configure a HTS rule to identify and drop messages with subject containing the word, “Meeting Forward Notification”.
