The Detect and Repair appears to have created a new mail profile and/or a
new PST.  WIth Outlook closed, open the Mail applet in Control Panel and
click Show Profiles.  See if there's more than one.  If so, choose the other
(i.e., the one not currently the default) to be the default profile opened.
If there's only one, select it and click Properties, then Data Files.  Add a
reference to the PST you had been using by clicking Add, browsing to that
PST, selecting it, and clicking OK.  Then click Close.  Click E-mail
Accounts>Next and change the "Delivery new e-mail to the following location"
drop-down to be the PST you just added.  Make sure your mail accounts are
correctly configured and re-add them if they aren't there.  Click Finish.
Click the Data Files button again and remove the reference to the extra PST.
Click Close, then Close, then OK.  Start Outlook.
