Ability to send from alias
This is such a basic feature that I'm actually surprised it's not possible. Please Microsoft fix this, other wise I'll be forced to use the iPhone basic mail :(
I migrated a client from GSuite to Office365 and they were angry that they lost the ability to be able to send from one of their aliases. It seems to be a simple functionality that really should be easily available. Please make this happen, it has been 3 years it seems!
