Outlook: Location messages are delivered to has changed for this user profile

Hi, I hope someone can help me ...

At work, I use Outlook 97 and received this message: "The location messages are delivered to has changed for this user profile. To complete this operation, you may need to copy the contents of the old Outlook folders to the new Outlook folders. For information about how to complete the change of your mail delivery location, see Microsoft Outlook Help.
Some of the shortcuts on the Outlook Bar may no longer work. Do you want OUtlook to recreate your shortcuts? All shortcuts you have created will be removed ".

I understand what the message means, but I am wondering what has caused this to happen. Could this be a result of someone playing around with the system? If so, does anyone know what would have been done?

Many thanks,
Jo S

 

Maybe?
