Good day all,
First of all a warm thanks to all people who contacted me in this thread or elsewhere and invested time and effort to fix the issue described in this thread.
Today it turned out the solution is very simple. And therefore I am kind of disappointed about all the so called specialists that have contacted me in the past couple of months. Volunteers, professionals, even official MS staff apparently had no clue what
they where talking about (or I described the issue in the wrong way).....
. . . . until . . . . Mark A from Microsoft contacted me and told me NOT to check EditProfile and tweak those email addresses, but to go to Security and change the SecuritySetting. Is a piece of cake, as indicated in the below screenshots.
