The ability to email a specific channel in Teams outside the application makes communicating a lot easier if you are juggling multiple things or don’t have time to log into the application. Once configured, you can email directly to any channel via any email service. Here is a step-by-step guide to configuring this feature:
First, open up Microsoft Teams and click on the ellipsis next to the Channel name and choose “Get email address“
Then, copy the email address associated with the channel, as shown below.
After that, compose your email and send to the copied address.
Now, everyone will see that email in the specified Channel within Teams as a message.
