What is Mio?

Mio makes it possible for users to send messages across Microsoft Teams, Slack, Webex, and Zoom so that everyone can chat with each other from their preferred platform. Say goodbye to managing multiple accounts or switching windows.

What does Mio not do?

Mio does not make phone or video calls interoperable, only chat messages. A full list of features is provided later in this guide.

Supported features

As a Microsoft Teams user, you can stay in Teams while chatting with colleagues who use Slack, Webex, or Zoom. That means you only need one platform to chat with users on all four.

Listed below are the chat features that are supported when sending messages from Microsoft Teams to Slack, Webex, or Zoom.

Channels

Synced channels

A synced channel is accessible by users on Microsoft Teams, Slack, Webex, and Zoom for cross-platform messaging.

  • Your admin has already synced a few channels and should have sent you a separate list.

  • Any message you send in a synced channel will be viewable by colleagues who use Slack or Webex.

Remember to check the table above for feature parity with Slack, Webex, and Zoom.

Unsynced channels

An unsynced channel is a regular channel that only lives on one platform and has not been made interoperable with other chat platforms.

To make a Microsoft Teams channel accessible to Slack, Webex, and Zoom users, first create a normal channel in Microsoft Teams (your organization may limit channel creation based on its policies).

Contact your admin with:

  • Channel name

  • Team that you created the channel in

    • The members you want to add to your new channel should already be members of that Team

Note: We currently do not support syncing private channels.

View channel membership

To check the membership list of your synced channels, navigate to your channel and click the · · · at the bottom. Select the Mio app.

The Channel Menu pop up will show and display the full channel membership.


Direct messages (DMs)

Starting a new DM

As a Microsoft Teams user, your admin has already synced your account with your company’s Slack workspace, Webex organization, Zoom organization, or vice versa.

To chat with colleagues who use a different platform, search for their name in the Microsoft Teams search bar to open the chat.

Send your first message to begin the conversation.

Sending and receiving cross-platform messages

When you send a message to a colleague who uses Slack, Webex, or Zoom, they will receive your message on their own platform.

You will receive messages sent from colleagues who use Slack, Webex, or Zoom in your Microsoft Teams tenant.

Mio allows you to send direct messages to your colleagues who don't use Microsoft Teams without the need for anyone to switch platforms.

  • At the top of your Microsoft Teams, use the search bar to find a colleague you want to message.

NOTE: Some features that work in synced channels may not be supported in DMs.


What should I expect to see as a Microsoft Teams user?

Your experience with cross-platform messaging should feel completely native, meaning every colleague you chat with will look and seem like they are also a Microsoft Teams user, even if they're on Slack, Webex, or Zoom.

In the below example, Susie is sending a message from Slack, but it looks like she's on Microsoft Teams.

If my colleagues are on Slack, Webex, or Zoom, why do they look like Microsoft Team users?

Great question. Your Slack, Webex, or Zoom colleagues are also licensed on Microsoft Teams. Mio syncs their Slack, Webex, or Zoom account with their licensed Microsoft Teams account.

Conversely, your colleagues receive your messages as if you were a Slack. Webex. or Zoom user.

Can I @-mention my colleagues who use Slack, Webex, or Zoom?

Yes! To @-mention and notify someone in a channel on Slack or Webex, type the @ sign and their full name as displayed.

The recipient will receive a notification on their platform.

@-mentioning is not currently supported on Zoom.
