I got outlook 365 for business for myself. I've created "Catch All" rule for any email to my domain to my personal email.
I want to be able to reply from original email address as if it existed in domain. How to set it up?
I registered to RandomStore using firstname.lastname@example.org email and read it when I login to email@example.com
How to reply to their emails from firstname.lastname@example.org? If I try to do it now I get "You don't have permission to send messages from this mailbox." error. This email does not exits in domain so I cannot set "SendAs" for this email.
