After reading several old forum topics I tried the Internet and found that
there is
actually something useful right in the Help section of Icedove, under
troubleshooting,
where there is a link to the actual storage location of my present icedove
profile,
and from which I copied it into the same location on the new computer's hard
drive.
After that, no luck. Upon starting Icedove in the new installation, there was
no hint
that the profile I want to use is there. Even the appearance of Icedove is
different.
On top of that, it wants my username and password, and my credentials are not
accepted.
I did force a new profile.ini to be created. Next time I'll leave it alone
and see ...
The "old" PC and the new PC are essentially identical Lenovo T420's.
Thanks,
George Langford
