I am trying to setup a third party e-mail alias to my Microsoft account. I am able to add it, but I do not get a security verification e-mail to verify my account or when I try to make it primary.
I can receive mails from Microsoft, no issue's with the spamfilter on that side. It simply does not send the verification e-mail. I am trying it now for several days, but I do not have a clue why this is broken.
Does anybody know what could be the issue? I see allot of topics on the internet related to this problem, but not a clear fix for it..
