I have two email addresses "me@mydomain.co.uk" and "me@gmail.com" provided by google. I have set my Gmail account to show all messages sent to and from Gmail as to show "me@mydomain.co.uk". i.e if I want to change providers my email address remailns the same.
Is there any way I can get Outlook 2016 to do the same, at the momnet I can not stop outlook showing my sent address as "me@gmail.com"

Any help would be appreciated
