Expected Behavior

Expect the bot to work in Microsoft Teams

Actual Results

No messages received by bot. I remote debugged using VS 2017 and no messages were received from MS Teams. All Slack and Skype messages were received.
For Facebook messenger, bot receives the messages, responds it, but the Facebook messenger doesn't display the response.

go to dev.botframework.com

in your bots page you'll be able to see the errors you receive per channel.

@xjose97x I don't see any errors on MS Teams yet no message is received by my bot.

@dynamicdeploy , can you check the errors on webchat?
I remember that sometimes the errors I received on Skype were actually shown on the webchat.
Not sure if it applies on MS Teams.

[dynamicdeploy]

No, I just double-checked. WebChat messages are the expected ones (timeouts). But MS Teams shows no messages.

@dynamicdeploy Did you "Side-Load" your bot into MS Teams app? With JSON manifest file, etc.?

This is a second step after you have added your bot to the Teams channel in the Bot Dev Portal at https://dev.botframework.com/

How to load your bot into MS Teams

Quick MS Teams bot deployment checklist:

• Did your O365 tenant administrator enable sideloading of apps for your organization?
• Did you create an app package
• Did you sideload your bot app into the relevant team?

Recommended reading:

• Getting Started with Bots for Microsoft Teams
• Create the package for your Microsoft Teams app - aka manifest.json file
• Sideloading your app in a team
• Testing your Bot

[dynamicdeploy]

I added to the dev portal and then just clicked the associated link to enable bot in MS Teams. I will try the procedure in the admin portal.

@dynamicdeploy Any luck with enabling the bot in Teams? Let me know if you are still having issues.

[dynamicdeploy]

Enabling sideloading worked. Thanks for the help.

I'm also seeing this issue for some reason. The bot seems at best unreliable at receiving the messages. Inspecting the web traffic, i can see that messages from Teams never hits the api endpoint i specified. However messages from the webchat goes through without issues. I have enabled the bot through side-loading, and it does seem to be working _sometimes_..

A colleague of mine tried writing messaging the bot from his user, and the first couple of hours didn't go through. Then a couple of messages got through, and then stuff kinda started falling apart again. If there a way of diagnosing this? It's a bit frustrating that the portal doesn't really tell us anything at all.
