My problem was that I had a PST file with a data synch error. When I migrated from 2013 Outlook to 2016 Outlook, and in conjunction with issues with my email provider, it became clear that the migration was failing. I decided to start again which meant I needed a capability to view my old emails. Coolutils Viewer was absolutely perfect. The only problem was that it was too good and it picked up all my old backup pst files as well. It has an automated search function which really it does not need. Anyway that simple to resolve, I just moved all my old files onto a drive and then deleted them from the C drive. It then picked up the emails and displays them just great including being able to print. A great utiity.
