Upgrade installations are and always have been problematic with Outlook,
even more so with betas. Best practice is install Outlook clean and use the

If you decide to experiment with an upgrade installation anyway, at the very
least you should create a new Outlook profile from scratch and back up all
data thoroughly ahead of time.

contacts, calendar, email, etc., or do I need to do something with the
outlook.pst file
