I am migrating from a PC & Outlook 2007. I exported 4 user email accounts to 4 separate pst files. I imported them into my Mac's Outlook 2011 and all the emails are in 4 separate inboxes. Do I now need to "Add Accounts" so that Outlook 2011 recognizes all 4 accounts again? I'd like to have mail from all 4 accounts show up in a single inbox.
