We have a Microsoft 365 business basic subscriptions. We'd like to add an alias email from other domain(s) for some accounts. Those aliases would be a read only mail addresses - email would be imported with IMAP application in our application.
Is it possible?
How to do that?
Do we need to define that other domain somewhere in MS 365?
How many aliases for one account can be defined?
What should be done that those emails are redirected to MS 365 Exchange instead of other mail server?
What's about quota for those alias mail?
