Exchange Server 2007 Beta2 Maximum Mail Stores

I was trying to work out the limits of the current beta of Exchange 2007 in terms of storage groups and mailbox stores and through experimentation I discovered that they are:

• Maximum Storage Groups: 50
• Maximum Mail Stores per Storage Group: 5

I guess that's a grand total of 250 mailbox stores then. That's a massive improvement over Exchange 2003!
