Online Status not Showing in Outlook

[Clippy]

Any ideas if this doesn't work? I checked the "Register Teams as the chat app for Office", I restarted, and the "Display online status next to name" box is still greyed out in my Outlook. I have uninstalled and reinstalled the office suite already and ran the repairs that my organization suggested. This is so frustrating!
