The limit is 16gb, not 6. Also, I'm 99% sure it's per store (public and
private) rather than total. The stores consist of the edb file and the stm
file (priv.edb + priv.stm, for example).
The stores grow as necessary to house their content, so for example if you
add 100mb of data, the database will grow by 100mb. If you then delete that
content, the store will not shrink accordingly. Rather, the freed-up space
becomes "slack" in the database. Next time you add content, it goes into
the "slack" space first, growing the database size only if there's not
enough slack available.
When you look at the logs of exchange's nightly maintenance in your app log,
you'll see entries like "private store has 100mb free after online
defragmentation." That's the amount of slack in the database.
To shrink the databases, you need to do an offline defrag using eseutil.
Since the databases will only start growing again anyway, and since there
may be a little risk in running eseutil, I recommend against it. The only
time you'd benefit from an offline defrag is if you permanently reduced your
storage needs, such as a permanent decrease in the size of your office. Or,
if you had a maintenance or corruption issue that called for eseutil. In
that case, you'd see errors logged warning you of a problem that required
your intervention.
