I made a mistake, I don't have a hotmail or msn address as my Microsoft account was created using my domain email address so when I logged into outlook.com it took me to MSN's inbox (hotmail) which then changed to outlook.com's new mailbox...nice!
The option to create am outlook.com alias was hidden away in mail settings so I created a new account using
[email protected] and at that point I found out that there was a feature to change email name in settings so I changed it to
[email protected] thinking it would free up first.last....no, it did not.
Realising that I'd created a bit of a pinch for myself I closed this new account and of course it says that everything should be gone in a few days but also mentioned 270 days... Logged out, logged in with my Microsoft account, went to create an alias but was told both the above aliases were in use.....
Bah! I'll have to wait however long it takes before I can enable the aliases above to my Microsoft account!
