I'm using Exchange 2007 and I've created a room mailbox. I want to know where the settings of the room mailbox are stored? What are the attributes used to store room mailbox information? Are they stored as AD attributes? How do I view them?

I know this is an old question, but I just had to look up the same thing.

You can verify that an AD account has become a room mailbox by checking the following attributes: msExchResourceMetaData -> ResourceType:Room

msExchResourceDisplay -> Room

msExchResourceSearchProperties -> Room

If you're trying to access the actual capabilities of the room (or other room attributes), you'll need to look at either msExchRecipientDisplayType or msExchResourceCapacity. The information in these tags is not very human-readable.

Here's a related question regarding those capability attributes: https://stackoverflow.com/questions/1588849/accessing-custom-resource-properties-of-a-resource-mailbox-in-active-directory

You may also wish to refer to TechNet: https://technet.microsoft.com/en-us/library/ee633491(v=exchg.150).aspx - The section called Resource mailbox attributes covers these settings slightly.

(For my conference rooms in Exhcange 2010, the msExchRecipientDisplayType is set to 7)


Every Exchange mailbox is always associated with an Active Directory user object; when you create a room or resource mailbox from Exchange, a corresponding (disabled) AD user account is created. The attributes for the mailbox are stored in that user account.
