ChrisWebbTech- Thanks. So to confirm, if I've communicated with someone in Teams, my conversation with them is forever in Teams? Take a user who was Islands before we realized Islands is awful and we needed to set everyone to SfBOnly… if I communicated with them from Teams while they were still Islands, I (as a Teams user) am never going to be able to chat with them and have it land in SfB on their side, right?
Also, do I understand from your response that I *should* be able to remove a conversation that's with a SfB user (aka has the Skype icon)? Because I definitely don't see a remove/delete/etc. option in the menu. The only difference between SfB and Teams conversations is the menu on a Teams conversation has "Manage Apps" in addition to Pin, Add to Favorites, Mute, and Hide which appear for both.
Sorry to go a little off the topic of presence, but the article makes it seem like this is pretty straightforward. Our experience with the Teams/SfB interop has been anything but straightforward. 😉
