Technician, your post at #6 above refers.
My most sincere apologies, I did not spot posts #4, #5 and #6 until this morning.
This is what I did to resolve my problem.
1. From Outlook 2010 click File>Account Settings>Account Settings
2. Click Change Folder
3. Click New Outlook Data File (This is just temporary)
4. Give it a name (I used "Test")
5. Click the + to the left of the folder name to expand the subfolders. Click Inbox. Click OK.
6. Then Click Change Folder
7. Click Select the one you want
8. Click the + to the left of the folder name to expand the subfolders. Click Inbox. Click OK.
9. Close Account Settings and click send/receive.
And this is where I found it.
It Is Solved: 0x8004010F: Outlook data file cannot be accessed.
Once again, I apologise most sincerely for not dealing with this at the time.
