Outlook 2007 works great with Win7. Did you make the profile from scratch or
use easy transfer to move it?

I would go to control panel, mail and make a new profile using a completely
new name. Add the old pst file to the new profile before opening Outlook.
If you get errors when you try to add it, the backup process may have
damaged the pst. Run scanpst on it and try to repair it or get another copy
from the backup.

See http://www.outlook-tips.net/beginner/scanpst.htm and
http://slipstick.me/scanpst for help and other tools that might be able to
recover it if scanpst fails.

I have just bought a 64 bit Acer Aspire X5810 to replace my box that just
died. The Acer came installed with Vista which I decided to opt for
upgrade
to Windows 7 before loading any other software. The upgrade was fine
until I
then ran the Windows Office Professional Plus 2007 suite of programs. All
seemed to have loaded fine until I came to use Outlook! The Acer box did
have a copy of Home and student Office 2007 pre loaded but I uninstalled
that
before loading my copy of WOPP2007 which I had used without a problem on
my
previous pc.

Initially Outlook would not load and returned an error message "No
profiles
have been created. To create a new user profile use the Mail icon in the
Control Panel". Even though it gave that message there was a profile when
I
looked via the Mail icon. After trial and error using support advice I
was
able to load Outlook and make a connection to my e-mail service albeit
creating a new pst file. My success was not fully rewarded because when I
tried to reply to some e-mails I received a further error message "The
operation failed an object could not be found". As a result I cannot send
e-mails even though when I use the test facility via the set up it reports
success for both receiving and sending. I have tried Microsft Fix It
which
simply wiped my profile completely and then I entered a new one which
created
another new PST file but still refused to let me send anything.

So I need to resolve the send problem but I also want to utilise the pst
file from my old computer which I had backed up before my previous pc
died.
However here I hit my second problem in that when I try to access the data
file via the File|Open|OutlookDataFile route it will not open any of the
files even though I can see them listed - will not even load the first new
profile file I created before the Fix It solution led to me having to
create
yet anoyther pst file. I have tried the import route into the new file
and
all I get there is another error message "Messaging interface has returned
an
unknown error". Have tried uninstall and reinstall and same problems
persist. Also used scanpst to repair the previous pst file and the issue
is
still there. I am more and more frustrated because I can see my large old
file siiting there but inaccessible and now I cannot send from the new
file
as well!

Is it too much to ask that W7 and Outlook 2007 should be more than
compatible? Help Anyone!
