Not long ago I switched to Microsoft Outlook 365 Classic for my email provider.

I managed to import everything I need from my old remail provider, including previously saved emails. Initially I was able to read my saved emails but now I can't.

When I goto my saved emails they are listed with my email address as the title accompanied by a date and a time.

When I try to open the saved emails I get the message This file cannot be previewed as their is no previewer installed

Any idea what is/maybe the problem and how to solve it.
