Vista64 / Outlook 2007 -- "Cannot open your default e-mail folders."

When I first load up Outlook 2007 in Vista64, I get a popup saying

"Cannot open your default e-mail folders. outlook cannot start because
a data file to send and receive mail cannot be found. To add a data
file, such as a personal folder file, double-click the Mail icon in
Windows Control Panel."


There is no mail icon in the control panel. Any ideas how to fix this?
I've uninstalled/reinstalled, same popup. When I click ok, outlook 2007
closes.

"I was able to research the problem and found out that it is from a bad
or corrupt profile. Not that that matters, but you need to create a new
profile and it can be done by going to start, run and type in the
following command.
outlook.exe /promptimportprf \\localfolder\outlook.prf
Answer yes to the prompt and reestablish your parameters for email
again. I did this and it fixed the problem immediately!"

Were you connected to an Exchange server? An .ost file is an offline file used with Exchange. You may need to connect to Exchange with your new profile and then sync a new offline file.
