Outlook creates a copie of every mail I send

[Theo]

I have 2 email accounts in @outlook.com. Now, after several years, I restarted using the oldest one again. But I see that every mail I send with it there is also a mail send to another mailaddress of me. However, that mailserver, being @tomaatnet.nl, stopped a few years ago. So it cannot be found by outlook any more. After several hours I get a message that the address is not valid. Of course it is not. Searching my account I cannot find anywhere that @tomaatnet.nl address. Searching the internet I now think that there is a rule in my account that creates and sends a copy of every mail I send. But I cannot see how that is done. Do not see in ccc nor bcc nor any option in system. Only in the outbox I see that at the same time the copy is send too. Using outlook.exe or thunderbird does not make a difference. I have two PC's. One is running Linux the other Windows and both send a copy. So the copy lookes to be created by my @outlook.com account and not by the mail program.
Where do I have to go to delete that copy sending?

Do you have a rule set up to forward mail to that address? Look in Outlook.com's Settings (gear icon) > View all Outlook settings > Rules. In Outlook desktop, look for an "after sending" rule.

Hello Diana,
That is the problem. I read in the internet about rules in Outlook but all settings are rule-empty. And in the options for creating new rules I read that only the incoming emails are related but not the outgoing. Sorry to say but I find understanding all the options in Outlook sometimes very difficult to understand what exactly will happen when you (de)activate it. Somehow, years ago, that @tomaatnet.nl is added by me as I am the only user of that older @outlook.com mailaddress but I cannot find where and how anymore.

Whether it’s always been your childhood dream to work for one of the best-known names in American cinema history, or you just want to see what it’s like working in the ‘happiest place on earth’ – for some, getting a job at Disney is like nothing else imaginable.
