First, it'd be nice if you didn't "hot-link" a picture in your
signature, just put the thing in there if you must have it.
Yes, this is normal operations for Exchange, the amount of white space
you have is of course going to depend on how active your mailbox stores
are. My most active/volitale store is just under 70gig right now and it
averages 250MB to about 600MB of whitespace. Note I said most active, I
have all VIP types in another store that is about twice that size, but
has next to nothing ever deleted, so has very little whitespace
(freespace). What your seeing is pretty normal in my opinion. As for
an off-line defrag, don't bother, it's not going to make a difference
for you.

Not having formal Exchange (or even messaging training) and wearing
so many IT/operations hats I often don't have time to do extensive
research, may I ask a question on free space?
Based on your suggestion, I took a look out of curiosity and my
application logs for ID 1221 seem to fluctuate with freespace values
from about a half-gig to only 3-4 MB after an online defrag completes.
1) I assume this is the normal DB maintenance occurring and is
nothing to be concerned about...?
2) This is the term "whitespace" that you're referring to?
TIA

Whitespace.
Previously used space stays in the database.
Unless you have a need to do an offline defrag (and based on the
information you've presented here, I wouldn't say that you do), don't do
one.

I was comparing the size of my database backups to my mailbox
level backups and I found a discrepancy of about 10 Gigs (Database is 35
GB Mailboxes are 25 GB). Is there some kind of overhead to the database
that I am missing?? Should I do an offline defrag of the stores? Just
curious, nothing earth shattering J Thanks!!!
Also, there usually aren't many log files because I do a full
backup every night and also each day an Incremental is done every two
hours. In other words, I don't believe log files account for the
difference.
