There is an ongoing issue with hotmail.
We are aware of that.
As for Gmail, I just told a user to use that for verification, it worked perfectly fine though
Yeah it's really strange because when i try it it doesn't work either. When we were told we had to use Yahoo, He made a Yahoo mail and checked his spam and his normal inbox, There was nothing there.
Then i tried and it didnt work either. Maybe because we live in the Netherlands?
