We received a call today where a meeting request sent to a Room mailbox shows the meeting organiser’s name in the subject line.
This can be rectified by running the following:
Set-CalendarProcessing -identity “meeting room name” -DeleteComments $true -AddOrganizerToSubject $true -DeleteAttachments $true -DeleteSubject $true
set-mailboxcalendarsettings -identity “meeting room name” -deletesubject $false -addorganizertosubject $false
Hope this makes your life a bit easier.
