For anyone who might be interested, I found the answer to this question in
the forum
www.office-outlook.com as follows:
> I was getting the same error message and this post guided me in the right
> direction. Somehow, my main Outlook file was "open" twice. To fix, in
> Outlook 2007, go to Tools menu, select "account settings", select the "data
> files" tab, and see if your Outlook PST file is listed more than once. If
> so, select "remove" for the one that does not show as your default.
