What you'll need before starting:
The Mio app installed in a specific team in Microsoft Teams
The universal channel link that your contact sent you (app.m.io/uc/abcde)
Part 1: Create a new channel in Microsoft Teams
If someone sent you an invite link to a universal channel, you need to first create a new channel in Microsoft Teams.
Next to the team you installed the Mio app in, select the · · · and select Add channel.
IMPORTANT: We recommend NOT converting your team's General channel as this channel is not fully compatible with Mio universal channels. Please create a brand new channel instead.
Fill out the desired fields.
Make sure Privacy is not private (The Mio app will not work on private channels, only public ones).
Then select Add.
Part 2: Joining a universal channel
Copy the invite link you received from your external contact. It should look something like app.m.io/uc/abcde
At the bottom of your newly created channel, find the "· · ·" and select the Mio app.
Paste the invite link into the bottom field and select Connect and join.
Congratulations! You have joined the universal channel.
