Getting error when using the option "Open Shared Calendar"

Question

Hello Everyone,
I have created four calendars for our office all of them for booking meeting rooms.
Three of the four work just fine but the fourth is being a pain.
I'm running Exchange 2010 and all our clients are running Outlook 2007. I have re-created
the meeting room a couple of times just to make sure I hadn't missed anything.
When I, or another staff memeber tries to use the "Open a Shared Calendar"
withing Outlook 2007 in Calendar view, we get the below error.
Cannot display the folder. Microsoft Exchange is not available. Either there are
network problems or the Exchanges computer is down for maintenance.
Any ideas why I'm getting this error?
Thanks,
Sean

Hi Sean,
Could you please check the conference room type,whether it is an Auto Accept or Delegate Type.
 checking the conference room type :
Get-CalendarProcessing conference room| fl *policy*
you may get the below results:
>Get-CalendarProcessing conferenceroom name| fl *policy*
RequestOutOfPolicy    : {}
AllRequestOutOfPolicy : False
BookInPolicy          : {}
AllBookInPolicy       : True
RequestInPolicy       : {}
AllRequestInPolicy    : True
If "AllBookInPolicy       : True" it mean it is an Auto Accept type and if "AllBookInPolicy : False" then it is Delegate type conference room.
If it is an Auto accept type then you should have Editor access on the concern room calendar to manage it and the same time if the room is an Delegate type you suppose to have Delegate access over the room.
To check whether you have permissions to access the room calendar.
