If you have an existing channel in Microsoft Teams, you can convert it into a universal channel and start inviting external contacts to chat with you.
Before you start
The Mio app will not work on private channels, only public ones.
The Mio app must be installed within the specific Team where your existing channel lives. Select the · · · next to your Team name and click Manage team. Then navigate to the Apps tab.
Using the Mio app extension
At the bottom of your existing channel, find the · · · and select Mio.
If you don't see the Mio app, make sure you correctly added the Mio app to your team.
Select Convert and invite.
Congratulations! Your existing channel is now a universal channel.
The link for the universal channel should start with "app.m.io/uc/" as shown below. Copy and paste this link to invite others to your universal channel.
If you're having trouble seeing the window, check if the Mio app was correctly installed to your team first.
