Microsoft Outlook Mail/Inbox

I downloaded Microsoft Office software and have been using Outlook for several months, but had to reboot my system today and now my inbox is empty and my folders are gone. Where would they be?

Did you log back into your user account during the reboot? If your inbox is empty and the folders are gone, you may be in the wrong account or you may have been using the guest account. Another possibility is that your Outlook data base became corrupt and caused the loss of your mail and folders.
