So I had a bit of a problem, I upgraded to Outlook 2010 and got this error when I tried to Send / Receive:

Receiving reported error (0x8004010F) : ‘Outlook data file cannot be accessed.’
Sending reported error (0x8004010F) : ‘Outlook data file cannot be accessed.’

So the way I solved the problem was

  • In Outlook 2010, Go to the File Tab and click on Account Settings
  • Click on the account you are having issues with and click on the “Change Folder” button at the bottom
  • Pick Personal Folders\Inbox and hit OK

Send / Receive All and your problem should be gone!!
