Hello,

This is about Exchange 2003 SP2. The total size of database adds up to ca. 21 GB (the limit is set to 25). The sum total of all mailboxes adds up to ca. 3 GB. The public folders etc. occupy another 3 GB. My question is: What contributes to the missing 15 GB?

Thanx in advance -
W.

Could be white space.  When was the last time you ran an offline defrag?

Its normally white space characters. Do users send lots of attachments to each other? if so then once they delete them they are still there in the dabatabase. check the "deleted items retention" period on my ur mailbox store. if they are at the default settings of 7 for deleted  items and 30 for deleted mailboxes. change them both to 0. take a full backup prior to all this of course.
then run the online maintenence. by defualt it runs every night at 1 am. once it finishes ull see an event id of 1221 that indicates how much free space youll have IF you perform an offlien defrag.

Check 1221 and see how much space you have. As people have said, it is probably white space. Take an ntbackup of the store and see how big that is - should be 15GB.

I'd recommend against an offline defrag unless you need the disk space. 12GB of white space is quite good. Leave DIRT as is but check it.
