I'm restoring an Exchange server from a backup:
 the backup was created on 19/12/2010
 the server kept running until 20/12/2010
 we're restoring the server today 21/12/2010 with the backup from 
My understanding is that when the server comes back:
 whatever is in users' inbox since  will be deleted.
 whatever is in users' sent box since  should be re-sent.
 As a safety measure we've moved all emails sent/received between  and  to .PST files.
-are  &  statements correct?
-is there any way to move back emails from the PST file  to the current inbox/sent folders so that Exchange takes these emails into account (instead of deleting them)?
-what happens to the Calendar items that were added after , is there any way to back those up as well if needed?
