Yes if you have Exchange 2003 Enterprise

No if you have Exchange 2003 Standard.

You can always Export mail to .PST files on the local PC's which would make space available in the Exchange Database, but this would not be free space on the server until you have passed the mailstore retention period AND run an offline database defragmentation, which means taking the store offline and running eseutil /d.

If you don't have space on the server (110% of the current database size (priv1.edb + priv1.stm), then you can use a switch to point the temporary database files to a drive that has the space:

eseutil /d /tx:\pathtodrivewithspace\tempdfrg.edb

clean up you current exchange server. That should give you lot of white space which can used for you new mails.

@mboppe - White space still takes up space in the database unless it is cleared out by running an offline defrag, so cleaning up the exchange server is just one step that needs to be taken.

kensy11 - Check your Application Event Logs and filter by Event ID 1221 - then look for the most recent entries for the Public and Private stores and advise how much white space is available for removal if you run an offline defrag.

If you have a read of the following article, you can reduce the mailstore retention periods, to allow the white space to increase and then at the weekend, once this has increased sufficiently, you could run an offline defrag:

@Alan

I know that. I was just telling him to clean up so that when he moves his mailboxes to exchange 2010 that would defrag the database.
Also white space would be used to any new incoaming mail. so that database won't furhther grow in size.

You probably know all the above.but wanted to clarify for Kensy
