You
aren't going to win this one.
If you
were to NEVER run eseutil again, you would have just as much space used on your
server. The 16GB limit has nothing to do with it.
The
DEFRAG process DOES NOT RECOVER SPACE!
Defrag
ONLY takes messages that are interspersed across the database and moves them to
the front of the database.
eseutil will COMPACT a database. But it doesn't recover any space. It
actually reduces the space in the database.
The
procedure that you are performing WILL REDUCE THE PERFORMANCE of your server. It
WILL NOT GAIN SPACE!!!
Look
at the database as a bucket. All day long you put in cubes and remove cubes of
various sizes. As you do this, the number of holes increases. If these holes are
relatively small, you can't stick a big cube in it's place and the space becomes
useless except for really small cubes.
Every
night, Exchange goes through the bucket and reorganizes the cubes, not only
once, but twice. So by morning, the cubes are packed really tight and there are
no holes between the cubes. Therefore all of the unusable space has been
recovered.
Exchange recovers the unusable space every evening, twice. All you are
doing is shrinking the bucket every night. Once you shrink the bucket, you have
to work hard to expand it. EVERY message that comes into your server during the
day forces your bucket to increase in size, resulting in a performance
penalty.
I will
absolutely, positively guarantee you that the process you are performing is not
giving you an advantage and actually has a high probability of causing you
problems.
