I've read this article. It does not give any examples for exporting multiple users at one time. Can you provide an example of how to do this? Do we need to create a .csv file with the users aliases that the script will call upon to determine which users to export?

Guys how can I export/import  multiple users mailboxes to a .pst file without exporting the entire mailbox store or doing one mailbox at a time?
Can you provide a command shell example that will export multiple users ?

Im also finding out that when I export a mailbox to a pst the the pst size is increased by up to 50% of the mailbox size and above. For example, I exported a mailbox that was 750mb. The pst for it was 1.8gb. Why does this happen and how can I avoid these large pst files? Im need to import these pst into another exchange 2007 server and Im afraid the large pst are going to cause problems.
Suggestions?

PST files bloat - the bloat can be anything up to three times or more. That is because they use a different structure to store the email - basically the email is stored in all three formats within the PST file.
