When it comes to replies, we always have to tag users even if you are replying to a comment from that person. If you reply to someones comment and you dont tag them, they don't even get notified, which is odd as you're replying directly to their comment.

It would be great if this could be updated so that it recognizes the people that were previously tagged, or who you are replying to. It's a bit tedious to always have to tag the same group of people.

We do love the feature to reply to comments from your outlook inbox, but when it comes to tagging users, this is not a feature that is available from Outlook. Tagging only works if you go into the CMP.
