How can I look up the Globally Unique Identifier (GUID) of an Exchange Server 2010 mailbox database?

In the attached screenshot, is the Globally Unique Identifier (GUID) of an Exchange Server 2010 mailbox database the set of numbers that I have circled?

    In the Exchange Management Shell run

    and this will list all the mailbox databases.  With Exchange 2010 all mailboxes are have to be unique.

    When you install the Exchange 2010 mailbox role on a server, exchange will automatically create a mailbox database with a random number as a suffix after "Mailbox Database". This is the numbers circled in you picture and you can see that you have two servers, each with a mailbox database on, and one with a public folder database.

    Typcially when you setup exchange 2010, you remove the default databases and create new one using some kind of naming standard.  For exchange I use

    where xxx is 001 to 999, remembering that the database name has to be unique.

    The circled numbers are not the GUID of the mailbox database.  If you want to see the actual guid run the following from the Exchange 2010 Management Shell:

    Get-MailboxDatabase | select Name, Guid

    Hope that helps
