Is the 75GB limit on Exchange 2003 for private + public, or 75GB for each?

I'm aware that there is a 75GB database limit on Exchange 2003 Standard SP2 (having updated the registry) but what I can't find anywhere is whether this is 75GB total of pub1.edb, pub1.stm, priv1.edb and priv1.stm, or 75GB for pub1.edb and pub1.stm and another 75GB for priv1.edb and priv1.stm. I'm assuming it's the latter, as the registry patches are one each for public and private, but we're approaching a total size of 75GB between the four files and I need to be sure it's not about to dismount. We're split evenly 35GB in public and 35GB in private.

It's for everything combined, Mailboxes+Public Folders
Alan HardistyCo-OwnerCommented:
It is 75Gb per database, so you can have 75Gb for priv1.edb and 75Gb for pub1.edb.
The size is virtual not physical!  It is a combination of .EDB plus .STM minus the White Space that can be overwritten within the file.
Alan HardistyCo-OwnerCommented:
White space can be determined by checking your event logs for event ID 1221 (usually around 5:00am) where you should see 1 entry per database.

Thanks for the quick replies. So you two seem to disagree as to whether it's a total, or 75GB for private and 75GB for public. I guess I need to wait and see what the majority opinion is, or hope someone posts a link to a Microsoft statement.
Mike ThomasConsultantCommented:
I think Alan is correct actually as iirc you can set different values for both?
Alan HardistyCo-OwnerCommented:
MojoTech is not correct unfortunately.
Please have a read of the following:
Exract - The Database Size Limit in GB setting is the configurable maximum size of a database.
A database is priv1.edb and another database is pub1.edb, thus the limit is 75gb per database and not a combination of the two databases which is why there are two registry settings to increase each database.
