First of all, thanks Denis and Steve for your replies.
Denis -- After removing Office 2002, for grins I installed a trial
version of Office 2007 Standard to try and isolate the problem as
Vista or Office, and Outlook 2007 works just fine; no problems with
remembering any of the email passwords.
Steve -- I already tried that procedure you linked to. Vista would
not let me remove that key. Don't remember exactly would it told me
but It was something like "Vista is unable to remove the key you
specified." I was in the Admin account, but not in safe mode.
I did try (prior to the install of Office 2007) to remove all the old
pst and account references, but Office XP found them. Don't know
where else Vista hides them, but did follow the path listed in Outlook
2002, so I though that I found it. After uninstalling Office 2002, I
again attempted to purge all the pst's and account references hoping
to start with a clean slate but Office 2007 even it was able to find
the "old" data (must not be looking in the right place). That
happened on both the Vista accounts I have set up -- one Admin and one
Limited. When I initially fired up Outlook 2007, it asked for the
passwords on the each of the accounts (since the previous software
refused to remember them), and it has remembered them since (including
several logoffs and reboots).
If I had hair to pull out, I'd be doing so but I'm afraid nature beat
Outlook to it!!
Things that make you go mmmmmmm.....
Regards, Clive
