Hey all Exchange 2000 Our Database (DB) is 15,1 GB big (the 4 files together) But the mailboxes together are only 4,2 GB! I know that exchange needs more space , and not only (in our case) 4,2 Gb, but check this out: A few days ago our DB was 16,1 GB big (the 4 files...) and the mailboxes together were 7,9 GB!!! i told my coworkers to tidy up their mailboxes, and now we have onl 4,2 GB mailboxes. shouldnt the DB shrink 4 GB ???? TIA Marco
