.pst file was corrupted by power failure on MS Outlook 2013. Microsoft repaired didn't aid me.

Hi,

Firstly you have to try ScanPST.exe which is free inbuilt utility to repair Outlook PST file. If this tool fails to repair Outlook data then you have to go with third party Outlook PST repair tool. I hope it will be helpful for you.
