Frequently asked questions

Can Mio access my private Teams and channels that aren't universal channels?

No, the Mio app can only view messages in Teams that is has been added to.

If you create multiple universal channels for different contacts under the same Team, your external contacts would not be able to access the other channels either.

Why does Mio need to read all files that I have access to?

When a file is uploaded in Microsoft Teams it's stored in shared Sharepoint folders. The Mio app needs to access these specific Sharepoint files in order to successfully send the file to Slack and Webex.

At this time, this permission is the least privileged scope that Microsoft offers.

Mio does not perform any other channel management actions other than for universal channels you create through the app.
