Outlook cannot start

hi,

shortly after upgrading from windows 8.1 to windows 10, Outlook 2013 stopped working. After the update everything was fine, but mid-morning it stopped working.

this error message:

"Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. File access is denied. You do not have the permission required to access the file C:\Users\Caleb\Documents\Outlook Files\[removed]."

i made no changes to outlook or any of the files. on perhaps a related note, a series of Windows updates failed to install, but ultimately did install successfully. A series of updates to Windows Defender have failed to install.

I tried replacing the suspect file indicated above with an earlier version, and the issue is still not resolved.

I put this question up on the Microsoft Community, and I got an answer that worked. here's the thread

I have my life back. On to the next panic.

i take it this was the solution :- http://www.msoutlook.info/question/pst-file-access-denied
