Have a Mac tower and Notebook, both OS 10.6.8_  Have been using Outlook on Notebook for 2 types of accounts and need both on the tower.  Just now finally installed Outlook on the tower.   Set up Exchange and one account (pop) works after import but need mail account on Exchange for work.  Error alert says "Unexpected data was encountered" when installed Outlook on Mac Tower and tried to get mail.  I have a backup on an external drive from Notebook that has been working.  Where to find Data to "import" to new setup?
