An administrator asked:
We’re using Exchange 2007 with a mixture of Outlook 2003 and Outlook 2007 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-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

Hi Ms Poremsky
Your information and tips are great! Unfortunately, there is a topic that I could not locate. That issue deals with items that the RECIPIENT (using OL2010) has access to. When a recipient opens the meeting request and sees the proposed time slot etc on the calendar, what other items from the SENDER’S (also using OL2010) calendar is the RECIPIENT privy to??
When I viewed my sent items folder, the view implied the recipient had the option to scroll through the sent calendar, thus viewing events from a variety of time slots… I am just a bit confused. Mega thanks in advance!

That is just an optical illusion. :) They can only see your free/busy, assuming they have rights to it. Others on your exchange server may be able to see free/busy but most people on other domains will not be able to see it.
