MicrosoftDidn't read the whole blog, because the frustration over poor design choices and self inflicted limitations got to high...
Instead of a development team creating a great product, we get a "well, that's just how groups, guest access, etc. work and we try to make our best. Here is some information about how you can work around it." Of course it's easier to dump comments in the group mailbox and telling every user that thinks he's just cleaning up a mailbox that he is actually deleting valuable information in another place, then idk choosing a better place to store comments. Where the user is expecting it?
The whole group mailbox design is such a disaster, I advice my user to just simply ignore it's existence. It's not acting as a real mailbox, so why bother to send email to it and even in really small groups of users creating a Microsoft Team for them is much easier to use and explain.
