An administrator asked:
We're using Exchange with a mixture of Outlook clients. Meetings are showing up on the Resource Room calendars with the meeting organizer's name in the subject line. How do we remove it?
This is an Exchange issue, not Outlook. It needs to be changed on the Exchange server using the Set-CalendarProcessing cmdlet to change the DeleteSubject and AddOrganizertoSubject settings for the resource room.
In Exchange 2010 and newer, use the Set-CalendarProcessing cmdlet. The format is the same as for Exchange 2007, using $true if you want to have the organizer name in the subject and $false to remove the organizer:
Set-CalendarProcessing -identity meetingroom -DeleteComments $true -AddOrganizerToSubject $false -DeleteAttachments $true -DeleteSubject $true
In Exchange 2007, use the set-mailboxcalendarsettings cmdlet to change the DeleteSubject and AddOrganizertoSubject settings for the resource room.
Use the following PowerShell command to make the change, changing 'meetingroom' to the correct alias for your meeting room.
set-mailboxcalendarsettings -identity meetingroom -deletesubject $false -addorganizertosubject $false
Set-CalendarProcessing (Exchange 2010/2013/2016/2019 and Office 365)
Resource mailbox's calendar shows the organizer's name instead of the subject in an Exchange Server environment (MSKB)
