Here's a handy tip on how to make a one-click link that opens a Teams chat to you or someone else.
Simply use the following URL for the hyperlink:
http://email@example.comFor example, I use a Teams icon in my Outlook signature that opens a Teams chat to me.
The link will open a web page where the user will sign-in with their Microsoft account. If the Teams app is installed on the client's computer, the web page will offer to open the chat in the Teams client, otherwise they can use the Teams web browser experience.
