I have discovered my carefully stored 15 years worth of emails now has little connection between subject title and content. The emails cover some important subjects like my mortgage, shares, insurance, and other legal documents extended guarantees etc.

The emails are mostly from various POP3 accounts I have had over the years and more recently,  live mail.

Of course I have backups which I have not attempted to restore yet, but they were also done using microsoft products.

The symptom is many titles all with the same content. I could probably tie the occurrence in with changing from 8.1 to 10 which didn't work very well.  After the most recent use of the windows repair tool and reloading my emails from back-up the emails I checked looked OK but now they are not (again).

So how do I recover this situation?

Any suggestions for other software that will read in my backups from outlook express etc?
