Do you mean Exchange Server 2003?  If so the mailbox size limit is 2 Gig but you can go larger.


The Standard Exchange server 2003 database size limit is 16 Gig but you can do a registry hack to make it a bit larger.

The Enterprise Exchange Server 2003 databise size is 16TB or hardware limitation.


If you want to go larger you will need to upgrade to Enterprise.

Not correct.

Size is only limited to number of files. NTFS has a a limit of 4,294,967,295 files on a volume.

There is no folder size limit:

Do you mean you are using the POP3 protocol on your Exchange Server?  If so, then, yes.

Yes that is what I mean. So if I limit email boxes to 16 meg I can have 1000 users store 16 meg each? Is that 16 gig for all web sites on the server?

You said there is a registry hack to make it larger. What is the hack?

Before you change the database size, be sure you have a good backup just in case something goes wrong.
