Re: Flow Emails are coming from the creator rather than Microsoft Flow.
Sure no problem.
Go to Office 365 Admin Center
Click Active Users
Select the user you wish to add the alias to
Their profile will appear
click on Edit to add alias
Add the alias
Change Display Name
(Make the Alias the primary email if you want the emails to come from that account)
Give it about an hour or so for it to sync across all applications.
Note if you make the alias primary you will need to sign in to Office 365 with the new email moving forward.
Hope this helps.
