What is the information store limit for Exchange 2003 Enterprise and Exchange 2007 Enterprise.

Can an Exchange 2007 Enterprise CCR have the same number of information stores and single Exchange 2007 Enterprise Server has?

Yes, you can have up to 50 information stores on an Exchange 2007 mailbox server whether it's standalone or part of a CCR cluster.  It's worth noting that whilst you can have multiple public stores on a standalone server you should only ever have one public store on any CCR cluster.  If you have more than one public store then you might get store corruption during a failover.

You can, of course, have 1 public store as well as up to 49 private stores without any problem.

Exchange 2007 comes in two version Standard (5SG with 5DB) and Enterprise (50SG with 50DB)

CCR comes with Enterprise Edition only. CCR works with 1:1 scenario. Means you cannot have more than 1 DB per SG. So you can have Active/Passive for 1 DB at a time. Still depends on Windows clustering.

You'll have one .edb file for each store, public or private.  You can have them in the same folder if you want, by MS recommends that they're on separate disks for best performance.

I'd recommend one folder per store at least.

You can have up to 50 stores in up to 50 storage groups, but you can only have a maximum of 5 stores per storage group. However, if you use CCR you can only have one store per storage group.

So on a single CCR cluster (a 2 node cluster) you can have 50 stores

The storage groups are only there for backwards compatibility.

Sorry, to clarify: 'store', 'information store' and 'database' all mean the same thing.

You can have up to 50 storage groups with a single information store  in each.

The terms 'Database', 'Store' and 'Information Store' mean the same thing.
