When Outlook won’t open, nine times out of ten, it’s a profile issue. You’re PST gets corrupt and Outlook just can’t open. Forunately, Outlook has a built in utility to fix just this…if you can find it.

The Utility is “Scanpst.exe” and it’s located in the C:\programfiles\Office(version number) folder. Bring up the RUN command and access it there, then point it to your outlook PST file. These are usually located either in the hidden folder “C:\Users\ (username)\AppData\Local\MicrosoftOutlook” or in an Outlook folder in your Documents folder. The initial error check is quick. Ten minuets or so, but further repairs may take hours. Be prepared.

Once done, Outlook should open normally.
