Back up file? How do you create that? Not rules? I have a LOT of
rules. This could be an issue.

I have been using OE only. I dunno, but I like the "feel" of the search
feature and layout of Outlook and I am still apprehensive that I will do
me some good instead of creating more work. I don't like OE's search
feel or layout. Hard to explain.

That's another issue. I spent a great deal of time one day in Outlook
deleting some emails that I didn't want. I guess the only solution then
is to delete all my accounts/profiles in Outlook and rebuild it from
scratch by importing it from OE. Again, looks like this will be tedious
and time consuming spending time deleting emails and recreating my
rules. Why can't the rules be imported/exported?
