We can’t always perform mailbox moves, cross forest moves or use web based mail migration service, such as Migrationwiz.com. From time to time we just have to get our hands dirty a shift PST files around.
If you have ever tried to use Exmerge to export a large (around 2GB) mailbox you will have run in to errors. Luckily Glen Scales http://gsexdev.blogspot.com/2007/01/exporting-mailbox-larger-then-2-gb-and.html and Michael Smith http://theessentialexchange.com/blogs/michael/archive/2009/10/16/exporting-mailboxes-larger-than-2-gb-on-an-exchange-server.aspx came to the rescue years ago.
I really like Michaels solution, I just edit the 3 lines below and run from the command prompt with cscript ExMBspanPst.vbs mailboxname.
servername = "EX01"
bfBaseFilename = mbMailbox
pfFilePath = "c:\PST\"
I thought I had seen the last of PST files, but we became reacquainted this weekend.
