Alias for contact
I can give my contact in Jabber a different display name that is easier for me to remember. But I couldn't do the same thing in Microsoft Team. I'd like to see this functionality added.
IBM Sametime had this function. Very useful for those of us memory challenged. I could add note about role or other reason I know them like: "So-and-So's Admin"
I think this is what I am looking for as well. Our accounts are set up as Mr.Lastname. So all our notifications say "Mr." because that is considered our first name.
Try bundling this with the Nicknames on Contact suggestion
