[mdlug] Mozilla profile - old emails not showing up?

[Harry Burleson]

I assume your old ISP (Roadrunner) used POP mail and the older messages are in a
cache in the Thunderbird profile you transferred from your wife's computer. I'm
thinking you might have to temporarily set up a new account to point to the old
profile; the local inbox for your new account will probably point somewhere in
your new profile.
