Alias, Account issue..

[AdSoftware]

Hi, All this is my 1st post.
I added an alias to my personal account and made it the primary.


All is well and signed out and back into everything.
My new alias is being picked up fine except in one instance..

When i send calendar invites out they arrive as being sent from:

outlook_feedxxxxxx@outlook.com

So obviously the recipients cant reply and it look bad..

It wont seem to refresh and the browser based outlook has the same issue..
