It took me a while to figure out whether this is a problem to troubleshoot or if this is by design. Here is the scenario.
User B is User A’s delegate. All messages received by User A has been set to be forwarded to User B.
When User A organizes a meeting with any user, this gets forwarded too.
But when User B forwards the same meeting request to any email ID, user A Receives this message:
From: Microsoft Exchange On Behalf Of User B
Sent: Date and Time
To: User A
Subject: Meeting Forward Notification: Updated: Subject
Your meeting was forwarded
User B has forwarded your meeting request to additional recipients.
Date and Time
All times listed are in the following time zone: (GMT-06:00) Central Time (US & Canada)
Sent by Microsoft Exchange Server 2007
Exchange 2007 (latest Service Packs)
This is by design in Exchange 2007.
We can disable the meeting forwarders by running the following cmdlet:
Set-MailboxCalendarSettings -Identity Alias -RemoveForwardedMeetingNotifications $true
In the above cmdlet: Alias is the alias name for UserA.
The above command disables the notifications that are generated to User A’s mailbox and is performed on a per user level.
