exchange 2010 databases and moving email accounts help


I have two exchange 2010 standard servers in a DAG. I have 4 databases on one that replicate to the other. I have one database on each that does not replicate. So I have 5 databases on each server.

I need to create new databases and move email accounts to free up tons of white space due to archiving and a handful of users leaving. I can't mount any newly created db because I am on standard and 5 is the limit. I have 3 databases around 200 GB each and one around 40 GB. I don't have much room left on the drive the databases are on.

I need help with a strategy to move mailboxes and then delete databases to free up room, preferably without adding much space to the drives.

Thanks for any help

Since it looks like you can't add any databases due to product limitations, the only options I can see would be to move all of the users off of one DB to other databases, delete the vacated DB, create it and move the users back.

Keep playing this round-robin until you have reclaimed all whitespace.

Otherwise you can run eseutil with the /d option to offline defrag your databases.

thanks for the reply ScottCha. That is what I figured. Will moving the mailboxes to another database take up additional storage on the drives? Meaning, if I move 100 GBs of mailboxes to a db on the same drive, will it decrease the available storage / take up more storage or will it just stay the same, except for logs but they are on another drive so won't matter here.

thanks again

That all depends.  White space will be used first and you won't see an increase until the whitespace is gone.

Example....You have a 100 Gig DB with 25 Gig of whitespace.

You move in 50 Gig worth of data, you'll see an increase of 25 gig for a total of 125 Gig.

Now those are rough numbers, but you see what I'm getting at.

If the white space you are moving to is greater than the amount of data moving in, then, no you won't see an increase.

thanks again ScottCha. I am going to try to figure out the white space and use the db with the most to move the mailboxes into. Luckily it's a VM so I can add a bit of space to get me through the moves.
