So I have a Microsoft account that I have been using to login to windows since windows 8, in the format email@example.com
The email for mydomain.com is NOT hosted with Microsoft, it is used only for login.
Then I decided to make use of Microsoft free email account, this was back when it was live.co.uk
so I added an alias of firstname.lastname@example.org
This used to work with the old windows live mail.
Since it has become outlook.com, everything has changed and I now have a problems.
It wants to use my primary login as the email address, which of course it cannot since it is not hosted with Microsoft.
If I try to add email@example.com to outlook desktop app, this doesn't work.It creates a user named "outlook_DE4D13B44.....etc" and won't actually download the mail.I cannot change my primary alias to firstname.lastname@example.org as this will break all the services which I have linked to my Microsoft account for authentication.Is there any way I can still have my Microsoft login as email@example.com but use firstname.lastname@example.org in outlook
