One day recently my Outlook failed to open. The error message was as follows:
"Cannot start Microsoft Outlook. The set of folders cannot be opened. File access is denied. You do not have the permission required to access the file. C:\Users\57gar_000\Documents\OutlookFiles\firstname.lastname@example.org."
I examined the pst file - I had full permissions, there was no read only box ticked. I then used the scanpst utility to repair the file. Repairs made, but still no joy. Advice?
