Hi,
I have an environment in which each user mailbox is configured with a PST file as the default delivery location for his\her emails. Each user's PST file is saved on his\her home drive on the file cluster. We will be doing exchange migration from 2007 to 2013. Now how can I do the mailbox migration alongside with the PST? Do I need to import first for all users their PST files into their current exchange 2007 mailbox then do the move or there is other way? We have about 900 mailboxes.
