1) You may want to try here:
http://www.microsoft.com/windows/downloads/stationery.aspx
These are for Windows Mail (ie Vista) but I'd think they'll work fine with
Outlook Express (but caveat emptor - and there seem to be problems with
animated stationery). MS don't seem to provide any for OE anymore, that I
can see (eg the site you now get to in OE from Tools > Options > Compose >
"Download More" stationery isn't exactly replete with them).
There are any number of other sites out there providing stationery if you
just search the web. But if you do that, you'll probably want to spell it
correctly, with an "e" not an "a". For instance:
http://email.about.com/od/freeoutlo...tationery_for_Outlook_and_Outlook_Express.htm
2) Outlook Express stops at version 6, there is no OE7. The next incarnation
was "Windows Mail" in Vista. Just be sure to keep your OE patched with
Windows Updates.
For further questions, you migfht want to try the Outlook Express groups
(there's even a "Stationery" one, although there's not a lot of activity on
it).
