Exchange Mailbox Limits

it depends, if you are using PST's it's 2gb if you are using exchange 5.5 non-enterprise you have a total limit of all mail boxes of 16gb. if you are using 5.5 enterprise it's unlimited up to the capactiy of your server.

Ross,

By default, Exchange server (both 5.5 and Enterprise) install with no limits for individual mailboxes. You can set them up. In teh Exchange Admin tool, you need to go to Configuration, then Expand the Server listing. Go to the properties of Private Information Store. There you can set global limits for all mailboxes. If you need to adjust individual mailbox limits, you need to go to the properties of the specific mailbox. There you can choose to use the global limit, or you can choose to set a specific limit for that particular mailbox.

I hope this is what you are looking for.

To the best of my ability to determine, there is no published information from Microsoft on a limit to the size of an individual mailbox. On a standard installation of Exchange, you could conceivably have an Information Store with a single 16gig mailbox.

As a practical matter, I become increasingly nervous as a mailbox approaches 2gig because the options for disaster recovery or server upgrade diminish once you can no longer export the contents to a *.pst file.
