Hi Roderick,

 

How is your setup done, what are the configurations ?

 

Is your domail btinternet.com the default domain ?

 

Are your users afected with the primary SMTP like btinternet.com ?

Do you have enough access to the domain DNS to complete connection of the domain directly into the Office 365 tenant via the Admin Center->Setup->Domains->Add Domain process? This is the only way I know of outside of having some kind of 3rd party forwarding service to allow an outbound email to show from the domain in question. It's much easier though and would be free if you can get access to the DNS profile.

 

If so you still have to go to Users->(Select User)-> Edit Username/Email Aliases-> configure the "Primary Email Address" for the individual user in order for the default outbound email to match the domain in question.
