Hi all,

I'm facing a trouble I don't understand.

I was out of disk space on a Win SBS 2008 so I decide to install new disks and move mailboxes of the exchange 2007 server on these new disks.

I create a new exchange database on the new disks, and then move all the mailboxes one by one to the new DB.

My problem is that I'm still out of disk space because the EDB file on the main disk is still big (17 gb) and I don't know hox to reduce it's size. Exchange is now blocking email reception due to this.

Any help will be appreciated !!!

Thanks.

François.

it will not reduce in size without an offline defrag but there should be no need to do this, just move all the mailboxes to the new store then delete the old store.

Please see my guide here: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2730-Exchange-Offline-Defrag.html

The old store will hold white space, the space is not recovered until there is an offline defrag.

the only issue with moving mailboxes to a new store is deleted item retention is lost

Mail are unlocked, they just came back in the system right now ...
