I'm just starting out with Exchange myself, but here's what we did to remedy this.
1. Set up the mailbox with one NT user as admin.
2. Log into the machine under that user, and log into Outlook under a profile for the meeting room.
3. Set up Resource Scheduling to auto-accept/decline so it will be self-maintaining.
4. Set permissions on the calendar for all users and for an admin if you wish.
5. Exit and Log Off and never go into that account again. - If you go back in, I've seen it break it.
6. Finally, whatever you do, do not set any Delagates - it screws the whole process.
After trial and error, I managed to break it quite a few times. To fix it, you need to make a shortcut icon to the outlook.exe file somewhere (I put it on my desktop).
Under properties for the shortcut, after the quotes on where the Target is, individually put each of the following and then run Outlook. Keep in mind this needs to be done while logged in as the meeting room account under the meeting room profile.
"..blah..\..blah..\outlook.exe" /cleanfreebusy
This should reset the free/busy options under that profile on the server.
/clean schedplus
Dunno exactly what it does, but something along the lines of cleaning the schedule.
These two worked for me for resetting the account to start again with setting auto-accepting meeting requests and adding them to the calendar.
FYI - there are a bunch of switches out there. Another one I have found useful is /cleanreminders.
Good Luck To Ya!
