Meeting requests sent to a room mailbox, replaces the Subject, with the Senders name
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: Exchange 2010/2013: Set-CalendarProcessing -identity “meeting room name” -DeleteComments $true -AddOrganizerToSubject $true -DeleteAttachments $true -DeleteSubject $true Exchange 2007: set-mailboxcalendarsettings -identity “meeting room name” -deletesubject $false -addorganizertosubject $false Hope this makes your life a bit easier.
