Microsoft 365 Group Mailboxes Can't Drag N Drop Both Ways

Tom_Keane_GCM - I'm glad I'm not the only one who is thinks this is a big issue. Like many other frustrations I have w/ MS, it's as if MS always seems to skip out on the "hey what obvious features are we missing" before releasing to public. Sadly, I've done a fair amount of research on this topic and it's likely that it wasn't due to MS "overlooking" this feature/ability, but it was intended to behave that way on purpose. And I don't know for sure but I believe it has something to do w/ standard email messages having the .PST file extension whereas "Modern Outlook Group" mailboxes use the .NST file extension to save/store the individual messages etc. (and I assume the original .PST gets converted into a .NST once dragged into Group mailbox). Again, this is my semi-educated guess. But again, where my main frustration lies, is MS needs to provide better info/clarity up front when releasing new features such as the "drag and drop from Pers Inbox to Modern Group" bc it's only natural for one to think you could easily drag back out of Group mailbox given how easy you can drag into Group mailbox. And MS, like with other app features/releases, should know this given they developed the program and just come out on the front end at the time of releasing the new feature to the public, with some sort of little caution bubble "hey the drag and drop functionality into MS Modern Outlook Group only works dropping into and cannot drag back out yadyadayada". Obviously even that's not ideal because I'd just prefer they allow to drag and drop back out but I'm sure there are coding/development/security reasons etc. as to why they can't, so just be transparent on that, before you put users/orgs. down creek w/o a paddle.
