The "toggle switch". In the past we had these checkboxes. A black square. If it had a x or check mark in it, it meant this option was active, otherwise not.

Now we have these fancy toggle switches. If it's on the left side, is it on or off? What if it's blue, or grey?

From my experience outlook flags emails as unimportant, that are quickly deleted, or deleted while being unread. So for me it's not too far off.

Once you decline a meeting, it's gone for good in your calendar. If you accidentally declined, you need to ask for another invite.

If you decline a meeting the original meeting will be moved to the trash. So go to trash and you can accept it again.
