@Sandie: this is the real strange point. It's neither the password for my PC (the new has has one), neither for the email-account.
For using Windows Livemail I shall enter the password for my internet-access- IP - but it shows the IP-code of my former account, used at the old PC - the IP-code, but never a password (except the hidden one, which works, every time, the PC was started). I never had a password for the Outlook Express-system, I had back there!
This ominous password
a) was never used/uploaded on this new PC
b) had to be changed due the new type of connection (now via FritzBox, the former was an old DSL-router)
c) as told above: there was no password for Outlook Express
Maybe I should go again to the computer-expert. He had my PC for cleaning it, when it was new. All the many useless pre-genereated programmes were thrown off, all the junk, which you never uses and which slows down power and speed.
The PC was a bargain offer from ALDI, a Medion Akoya with 4 GB-working memory and a harddrive "1000 GB S-ATA"
Not bad (as me as a total computer-non-expert can overlook, and as the other owners are saying in internet-forums), but the problem is probably not caused by the machine itself, rather it has something to do with the internet-access. It took several weeks to solve that, caused by the stupdity of the provider, where noone was able to understand, what I have meant. Finally it was fond out, that the old IP-address cannot work with the new way of connection, the FritzBox.
So finally I was really happy, when I could use my new PC for the internet (at least nearly the only thing, I do with it, plus collecting our photos), that I don't bothered about the mail-problem. But I became more and more unsatisfied, because it's a big obstacle.
