Resource Mailbox’s Calendar Shows The Organizer’s Name Instead Of The Subject

In an Exchange environment, when you send a meeting request to a Resource mailbox, the meeting request is accepted automatically as expected but the meeting subject is replaced with the organizer’s name.

Why?

This is default behavior of a resource mailbox. It occurs because AddOrganizerToSubject and DeleteSubject parameters are set to “True”.

Let’s take a look at these settings with the Get-CalendarProcessing cmdlet:

Fix

To resolve this issue:

• Open the Exchange Management Shell.
• And run the following cmdlet:

  PS > Set-CalendarProcessing -Identity <RESOURCEMAILBOXNAME> -DeleteSubject $False -AddOrganizerToSubject $False

You just have to close and reopen your Outlook.

It also works on Exchange Server 2016.
