Outlook Android/iOS app - send as distribution group

Like how you think it should work ?

we have email, for e.g. info@vzv.cz, shared to a few users, and we need to send mail as this mail. But send it like .. the user with the mail shared will log in to App .. write a mail, choose a mail thru which he want to snad as and send. I think your solution would work like that the user will have to log out from his personal mail a log in to this "shared" info mail.

But thanks for opinion :)
