Does anyone know the max out of box database size for Exchange 2007? Or does anyone know what the max database size will be able to become with registry edits? THanks.

Hi,If you mean the quotas when send and/or receive are prohibited you can find them using the following Exchange Management Shell command:get-mailboxdatabase | format-list prohibit*The quotas are approx 2GB in Beta 2.I don't know if those will be the final quotas at RTM.Andrew Watt MVP

If you mean the max size of an edb database, youreally wouldn't need toworry They can be many terrabytes, so it rather the max size you want to allow you should think about (having DR in mind)

I read earlier that it was 16 TB per database, and only because it was hardware limited....I think I saw it off MS website, but who knows...

As Henrik was saying just because you can doesn't make it a good idea. You will still need to be able to backup/restore and do maintenance on the database.

The theoretical limit is 16 TB per database. However, generally database size is restricted by things like SLAs, RTOs, etc. You can see our current Beta 2 recommendations for database size at http://www.microsoft.com/technet/prodtechnol/exchange/E2k7Help/7d63f5d3-690a-47db-95cd-20ecace1c867.mspx. Note that the recommended size is based on whether or not continuous replication and gigabitethernetare being used. Hope this helps.

Will this 16 TB limit apply to both Standard and Enterprise Editions? Or, will it be lower for Standard Edition? Currently, 2003 Standard has amaximum sizeof 16 GB (75 GB with SP2), and 2003 Enterprise has a maximum size of 16 TB.
