| DO keep an eye on transaction log space, and be sure to NOT run any ESE backup operations during the merge. If you had 150GB of content before the disaster, then that merge has to put 150GB (and a relatively similar amount in transaction logs) of content back into the new dial-tone database.
I'm not sure how the Mailbox Merge/RSG process handles SIS. I'd originally heard that some of the code came from ExMerge, which would indicate broken SIS. Like Michael said - it won't be anything you can calculate ahead of time and plan for...but if you have a single store in your environment AND
it's 150GB, there's probably lots of SIS space savings in there. Be sure you have a LARGE cushion of free space available where your DB is stored.

This is because Exmerge "breaks" SIS - Single Instance Storage. I can't tell you how important SIS is in your environment without knowing a lot more about your environment. In most environments, it's relatively UNimportant. Microsoft has recommended since at least the release of Exchange 2003 that
SIS NOT be taken into account when planning disk utilization for Exchange.
I've marked this OT since we are drifting far afield from Active Directory.

I hear that ex-merge will increase the size of the database considerably, because any email sent to a group will get copy to all the mailboxes instead of being a pointer.

That's basically what the "mailbox merge" process is, depending on your version of Exchange.

Wouldn't exmerge be of any help by exporting/importing the mailboxes?

Well, there are two ways to do this, based on your backup situation.
Right-now, if you built your recovery server properly (which it sounds like you probably did, since your users are receiving new email), you have what is called a "dial tone" server. What you need to do is a dial tone recovery.
Dial tone recovery, in all its glory, is covered in this white paper:
http://technet.microsoft.com/en-us/library/aa998947.aspx
Basically, you've already "reset the message store". What you'll do next is "restore" the old database files to the new server, reset them to deal with database portability, mount them in a RSG, and then use the mailbox merge process to move the users data into their live mailboxes.
Read the white paper. It's pretty good.

HI,
Our Exchange server 2003 got destroy by the water, so I build a new exchange server with the same name and put it back in the network, so the users are getting emails again but they can see their old email. Later, I was able to revive the destroyed email server by changing the motherboard
in that server.
My question is, how can I move the emails from the old emailserver1 to the new emailserver1? I have full access to both, should I use recovery store? I cant put the old one in the network since it was also a DC (I manually remove that from AD).
Not worry about public folders.
What files do I need to copy? The priv take almost 150 gigs.
