Hi there,
I know this isn't a software suggestion forum, but I had liked to know a better alternative to MailStore. It is appreciable at archiving my Outlook emails. The only problem I face is at retrieving them back. I find no option to do the same.
I use Mail Backup X on Mac, and that seems much faster at archiving the emails and easier at retrieving my mails back.
Is there any better solution on PC?

The problem is resolved now. I continued with Mail Store for a few more weeks. Lately I found, the developers have released the Windows version as well. That helped.
