I recently upgraded both of my computers from Windows 8.1 to Windows 10. Outlook 2013 (Office 365) ran perfectly on both computers for a relatively short time, then started denying access to the PST (Personal Folders) file. For example, yesterday on my laptop I could move emails into folders in my PST just fine. Today when I tried to do the same thing, I saw the message "File access is denied. You do not have the permission required to access the file, then it references the location of my PST file. What is really odd about this situation is that it happened during normal processing - fine one minute, then access denied. Now I cannot access anything in the PST on either of my computers. In the interest of full disclosure, I am running Norton 360 for virus protection. a
I am wondering if I should roll one of my computers back to Windows 8.1, rebuild the Outlook profile or other. Thanks in advance for your advice!
