I have sort of a weird situation that I need to get solved.
We use office 365 (exchange online) for our email server.
My company is going through a rebranding. Currently, we have one domain that we have, @companyname.com, they are trying to add a new domain, @newcomanyname.com. What I am hoping to do is add a proxy address for all the users in @companyname.com domain for the @newcompanydomain.com.
For example, user@companyname.com would be able to receive email at both user@companyname.com and user@newcompanyname.com. I know that the proxy address can be done, the main question that I have is, can we have the users send from the proxy address @newcompany.com. If we can how can we do it?
If you have any questions or need more information, please let me know and I wil provide what I can.
Thanks for the assistance!
