Resource mailbox's calendar shows the organizer's name instead of the subject in an Exchange Server environment

Summary

This article describes a behavior in which a resource mailbox calendar displays the meeting organizer's name instead of the meeting subject. This behavior occurs by design when the AddOrganizerToSubject and DeleteSubject calendar processing settings are enabled on the resource mailbox. To display the original meeting subject, configure the resource mailbox to preserve the subject and stop replacing it with the organizer's name.

Symptoms

Consider the following scenario:

• A Resource mailbox is configured to AutoAccept in a Microsoft Exchange Server environment.
• You send a meeting request to the Resource mailbox.
• The meeting request is accepted automatically, and the meeting subject is displayed correctly in the organizer's mailbox.

In this scenario, when you log on to the Resource mailbox, you see that the meeting subject is replaced with the organizer's name.

Cause

This is default behavior. It occurs because AddOrganizerToSubject and DeleteSubject are set to True.

To view these value for the Resource mailbox, run the one of the following cmdlets:

• For Exchange Server 2016,Exchange Server 2013 or Exchange Server 2010

  Get-CalendarProcessing -Identity <RESOURCEMAILBOX> | FL
  

• For Exchange Server 2007

  Get-MailboxCalendarSettings -identity <RESOURCEMAILBOX> |FL    
  

Resolution

To resolve this issue, follow these steps:

1. Open the Exchange Management Shell.
2. Run the one of following cmdlets:

   • For Exchange Server 2016, Exchange Server 2013 or Exchange Server 2010
