Making Teams the default conversation app in Outlook

[Jacques Alexandre Bergeron]

When you mouse over a user in Outlook you have a icon the start a new of conversation. This automatically open Skype. Is there a way this open Teams instead?

You can but you must be on Teams only mode for this to work and a newish office build 1810+

I am in TeamsOnly mode and if I go to settings on desktop client (my photo, settings) I can see a checkbox for this option "Register Teams as the chat app for Office (requires restarting Office applications)" If you can see this option, then check it on :) And you need a recent Office build too like Chris stated. I can't check at the moment if this requires the TeamsOnly mode too (but I suspect it will - again like Chris said).

Not so sure it does require teams only! I’ve set this option a while ago and was on island mode and had this working!

Can’t find any documentation or release note about this feature. Do you have any reference I can read on this?

You can make Teams your chap app for Outlook without being on teams-only. The setting however is found in Teams, not in Outlook.

Teams Screenshot

In Teams, click on your User Account Icon (photo or avatar) to the top right in the title bar.

Click Settings.

Check the "Register Teams as the chat app for Office" checkbox.

Restart Outlook and Hey Presto! You can now click the Conversation icon and it starts Teams!
