Hi!! I have Exchange 2003 SP2. The PRIV DB has these values (Priv1.stm 21.2GB, priv1.edb 16.5GB ). I deleted many mailboxes but no reduction in size. I understand that for the reduction is due to perform a defragmentation Offine Questions: 1 .- advancement can know the size to stay the priv1 after defragmentation? " 2 .- I have space for defragmentation? 3 .- run parameters?, Is reliable? Thanks

1. Events 1221 in the app log will tell you the minimum space you will recover: http://support.microsoft.com/kb/186291 2. You need 110% of the actual size of the store free to do an offline defrag. 3. There is typically no need to do an offline defrag. Why do you want to do this?

In addition to what Andy stated, to gain that space back immediately you can perform an offline defrag but I would make an extra offline copy of your database before performing. I prefer to be extra safe when performing any defragging of databases. MVP Exchange Server

I would like to reduce the size of the priv1, either for backup and performance has never been done this action since 6 years he has installed. The event 1221 tells me decreased that 5450 MB. The steps would they?: 1 .- Exchange NTBACKUP 2 .- ESEUTIL / D "FOLDER/priv1.edb"

That 5GB of whitepsace will be reclaimed by Exchange before growing the store size on disk.. I would recommend against this and leave it be.

OK, so I do compaction. Where then do you recommend?

5 GB is not a huge space for exchnage database, you can leave it as per AndyD suggetion, If you really want to rduce the space, create one Storage Group {if you have 3 Storage group current} move all user from one storage group {all mailboxdatabase} to newly created storage group and again move all user to old storage group it will clear the whitespace of the database. You can do this activity one by one storage group.Dinesh

Currently the DB is 25GB and the event tells me that compact 5GB. have only one Storage group . Standard version I have, I think it allows more.

I would do nothing. That 5GB will be reclaimed at some point anyway. Compacting it will really gain you nothing. Why bother? It requires downtime and is not needed.
