Teams online meeting prep checklist

  1. Make sure your laptop computer is plugged into power.
  2. Make sure your laptop is plugged to wired-internet.
    1. If it is not possible to plug your laptop to wired-internet, make sure all other devices that use your internet at home are shut off, or you have configured your router to prioritize internet traffic from your laptop.
  3. Make sure your laptop’s camera is at your eye-level. You may use some books to raise the position of your laptop on your table.
  4. Use a warm light placed behind your laptop to ensure your face is well lit.
  5. Make sure to look into the camera when talking to others during the online meeting.
  6. If you are going to share your screen, ensure that your screen is at 1920×1080 resolution for the widest compatibility.
  7. If you are going to be giving a presentation, consider using PowerPoint presentation coach to tune your speed, pitch, etc.
  8. Start with a strong well throated “hello” / “hi”, and consider memorizing your opening.
  9. Solid colors are preferable for clothing. Avoid very light/white.
  10. Sit straight to ensure your lungs get enough air/oxygen and you stay in the zone.
  11. Find a spot with good background instead of using background blur, if possible.
  12. If meeting with a lot of people, just remember that you are basically talking to each of them individually – i.e. 1000s of 1s.
  13. Consider taping a card-stock A4 paper behind your laptop with painter’s tape to remind yourself of key points, and to look into the camera!

Here’s another handy image reference of the key points:

All the best!

How to @ mention people in Teams using Flow bot?

TLDR; Steal the card JSON below and create your Flow such that it provides the Name and AAD ID of the user to be mentioned at the highlighted spot and you are good to go!

Let’s say you decided to automate some workflow in your team using Flow so that it posts a message in a certain channel whenever some items satisfying some condition are detected.

In a software engineering team, for example, this could be a Flow for alerting the team about bugs that are older than XX days.

Well you set this Flow up but now you find that folks miss the messages from Flow bot in the channel and don’t take action, so you wish there was a way to @ mention the person that the bug is assigned to and get their attention.

Well now you can do just that: use Flow bot to @ mention the person that the bug/item needing attention is assigned to.

Use the following sample Adaptive Card JSON and make the following tweaks:

  1. Make sure to provide the name you want shown in the mention.
  2. Make sure to provide the ID of the user to be mentioned in the card in the following format “8:orgid:<AAD_ID_OF_USER>“.
    "$schema": "",
    "type": "AdaptiveCard",
    "version": "1.0",
    "body": [

            "type": "Container",
            "items": [{
                "type": "TextBlock",
                "text": "Stale bug alert!",
                "weight": "bolder",
                "size": "medium"
            }, {
                "type": "ColumnSet",
                "columns": [{
                    "type": "Column",
                    "width": "stretch",
                    "items": [{
                        "type": "TextBlock",
                        "text": "<at>Sid Uppal</at>",
                        "weight": "bolder",
                        "wrap": true
    "actions": [{
        "type": "Action.OpenUrl",
        "title": "View bug",
        "url": ""
    "msteams": {
        "entities": [{
            "type": "mention",
            "text": "<at>Sid Uppal</at>",
            "mentioned": {
                "id": "8:orgid:6b7b3b2a2c4b4175858241c9e685c1b5",
                "name": "Sid Uppal"

Note that the ability to @ mention users in Adaptive Cards is available in Public Developer Preview at this point (ref).

Your teams fav playlist 🎵💗

Ah, music!

There’s nothing like some great music to help you focus on work, stay in a state of flow, and get stuff done. Here’s something fun you can do with your team: you can wire stuff up with Flow, so your peeps in Teams can all come together to build a common Spotify playlist which plays on a set of speakers in the open-office area where your team works! You can also fire up this playlist at a morale event, a product/release ship party, holiday party, or on a Friday afternoon to lift everyone up.

This article shows you how to get this going.

Skill level required: low.
Excitement level generated: high.

Here’s what will happen once you’ve wired everything up.

Anyone in your team would be able to go to the “Community Playlist” channel, or whatever you want to call it, and share a Spotify song link.

This song will magically 🌟 get added to the Spotify playlist that’s playing on a set of speakers in the common area where your team works!

OK, excited to figure out how to make this work?

If you are impatient, just grab this Flow package and import it. Follow the prompts.

Psst, to import… just go to and tap on Import in the top ribbon.

How does this Flow work, you ask?

Here’s the overview.

Let’s break it down!

“When a new channel message is added” piece is our trigger. There’s nothing very exciting here, except that, this is where you specify the channel in Teams that should be monitored for new messages. This is the channel you’d ask your team to share the Spotify songs to. The interesting stuff follows this step.

BTW, here’s a cool tip: this trigger is a pretty powerful way to easily light-up a bunch of scenarios for triggering things in other systems based on stuff posted in Teams. Think about that. 🤔

“Parse out Spotify song URL” is slightly more interesting. This is where we do some Flowjitsu™ to parse out the URL to the Spotify song in the message. Nothing extremely fancy here, than to just find the index where the Spotify URL starts and rip out the complete Spotify URL to send off to the next step.

“Build a Spotify song URL” This is straight-forward as well. The only minor tricky thing here is to realize that the next step for adding tracks to playlist requires you to send URIs of the form “spotify:track:<bla>” so we do some simple string replace.

“Add Tracks to Playlist” is straight-forward as well once you’ve got the rest of the steps right. It receives the “spotify:track:<bla>” URI from the previous step, and needs to be given the ID of the Spotify Playlist to add the song to. You can grab that using the Spotify client via the … next to the playlist name as shown here.

👉 Go ahead, try it out! Go to the channel you decided on, and paste a Spotify song link you get in the following manner.

… next to a song, tap Share and then select “Copy Song Link”

It should get added to the Spotify playlist you configured.

And that’s it! Done! Go show off to your team! 👍

You are welcome!

Send a notification to a Microsoft Teams user from an app


This article describes a solution for the scenario where an app needs to send a notification to a user in Microsoft Teams.

Overview of the solution

This can be accomplished by utilizing bot support in Microsoft Teams as illustrated in the diagram below.


  1. Bot Framework SDK sends an Activity object to the bot whenever a new message is received by the bot from a user.
  2. This Activity object contains a bunch of information, but of most interest to us for this scenario is the conversationId and serviceUrl. It is referred to as CallbackInfo in this diagram.
    1. conversationId: Each bot:user 1:1 chat has a unique conversationId.
    2. serviceUrl: serviceUrl informs the Bot Framework SDK where to send the HTTP request with bot’s reply.
  3. ConversationId and ServiceUrl (and bot-id + bot-secret) are enough to post a message to the conversation. So the idea is to persist the combination of ConversationId and ServiceUrl mapped to the userId of the user.
  4. When an event occurs in the system that’s of interest to a user, now it is possible to lookup the corresponding CallbackInfo and post a message to bot’s conversation with that user.
  5. The sample code below illustrates how to compactly store the CallbackInfo as a token in a webhookUrl and how to implement the webhook handler to post to the conversation of the bot with the user.


Sample code

Here is some code to illustrate the key parts of the solution.

First, here’s the class that captures the CallbackInfo.

public class CallbackInfo
    public string ConversationId { get; set; }
    public string ServiceUrl { get; set; }

Here is how one can construct a webhook URL that contains the encoded CallbackInfo based on the incoming activity received when a user sends a message.

 var callBackInfo = new CallbackInfo() 
     ConversationId = activity.Conversation.Id, 
     ServiceUrl = activity.ServiceUrl
 var token = Convert.ToBase64String(

 var webhookUrl = host + "/v1/hook/" + token;

And finally, here’s a sample webhook controller that can post to conversation with user:

public class WebhookController : ApiController
    public async Task<HttpResponseMessage> Handle([FromUri]string token, [FromBody]IncomingMessage message)
        // Unpack the callback information
        var jsonString = Encoding.Default.GetString(Convert.FromBase64String(token));
        var callbackInfo = JsonConvert.DeserializeObject<CallbackInfo>(jsonString);

        // Post the message onto the conversation with the user
        ConnectorClient connector = new ConnectorClient(new Uri(callbackInfo.ServiceUrl));
        var newMessage = Activity.CreateMessageActivity();
        newMessage.Type = ActivityTypes.Message;
        newMessage.Conversation = new ConversationAccount(id: callbackInfo.ConversationId);
        newMessage.TextFormat = "xml";
        newMessage.Text = message.Text;

        await connector.Conversations.SendToConversationAsync(newMessage as Activity);

        return new HttpResponseMessage(HttpStatusCode.OK);

Using this approach in the real world

  • Securing the webhook: Use an HMAC in the webhook URL to ensure that POST to webhook is coming from the legitimate app (example).
  • Slack message schema: Is the app/service only able to send messages in Slack webhook format due to legacy reasons? Consider using classes already defined in an existing nuget package to deserialize messages coming in. Slack.Webhooks looks promising, though I have no personal experience with it.
  • Consider cards: You also have the option to post cards from your bots to get the attention of users. Take a look here.
  • Authentication: Look at AuthBot for how to utilize OAuth within bots to authenticate users (link).
  • More about activities: Read up about Activities in Bot Framework documentation here.
  • Write your first bot: Looking for a step-by-step instructions on how to create a Microsoft Teams bot? Take a look here.

Creating a bot for Microsoft Teams


This article presents step-by-step instructions for creating a new bot using Bot Framework and side-loading it into Microsoft Teams for testing.

Let’s get started…

  • Download the Bot Framework Visual Studio C# Bot project template using this link.
  • Copy this zip file over to Documents\Visual Studio 2015\Templates\ProjectTemplates\Visual C# on your machine.

Create a new bot!

  1. In Visual, click on File -> New Project
  2. Select Bot Application and hit OK.


Time to wire it up!

Register your bot in Bot Framework and update your bot’s config

  1. Go to and select Register a bot, or simply click here.
  2. Fill out the Name, Bot handle, and Description.
  3. Leave Messaging endpoint blank for now. We’ll come back to this in a bit.
  4. Click on Create Microsoft App ID and password.
  5. In the new window that pops up, click on Generate an app password to continue.
  6. That will cause a popup to show on the site with your app’s password. Copy it to your clipboard.
  7. Now switch to the Visual Studio solution you created earlier and open the web.config file.
  8. Paste the password you copied into the value for MicrosoftAppPassword key.pastingapppassword
  9. Now switch back to the window where you copied the password from and hit Finish and go back to Bot Framework.
  10. Now back on Bot Framework’s bot registration page, copy the value of Microsoft App ID and paste it into the value of MicrosoftAppId key in the web.config file in your project.
  11. Copy the value of Bot handle as well and paste it as the value of BotId key in the config file.
  12. Double-check that you copied the values for BotId, MicrosoftAppId, and MicrosoftAppPassword correctly.
  13. Now hit F5 to start Visual Studio with debugging on.
  14. Make note of the port number used in the browser that opens up.
  15. We are not done with registration in Bot Framework yet – we need to tell Bot Framework where to post messages meant for our bot. We will come back to that very soon.

Test your bot

  1. Download ngrok from here and extract the zip file.
  2. Launch Command Prompt and change into the directory where you extracted ngrok.
  3. Now this is where the port-number your site is running on comes in.
  4. Run the following command: ngrok http 3979 –host-header=localhost. Replace 3979 with whatever port number you saw earlier.
  5. This will start an ngrok tunnel. Copy its URL.
  6. Now, connect Bot Framework to this tunnel in the following manner:
    1. Go back to the Bot Framework registration page for the bot.
    2. Paste the following value for Messaging endpoint: <your_tunnel>/api/messages.
    3. In my case that is
    4. Accept the Privacy statements, Terms of use, and Code of conduct (after you’ve read them, obviously) and click Register.
  7. Now click on the Test button under Test connection to your bot.
  8. You should see a successful POST /api/messages request received via your tunnel.
  9. That ensures that you have plugged everything in properly.

Test your bot inside Microsoft Teams

  1. Find “Microsoft Teams” under Add another channel and click on Add.
  2. In the window that pops up, ensure that the channel is On and tap on I’m done configuring Microsoft Teams.
  3. Now simply click on the Add to Teams button to side-load the bot into your Microsoft Teams and start a 1:1 chat with it.
  4. This would launch Microsoft Teams if you already have it installed and bring you into a chat with the bot. If you don’t have Microsoft Teams, continue to download it, sign-in, and click on Add to Teams again.
  5. Send a message to your bot and you’ll find that it responds with the number of characters in the string you sent. That’s the default logic in Bot project template.
  6. Congratulations! You’ve got your bot working.

What to do next?

  1. Understand how everything works: Set breakpoint in MessagesController.Post method and send a message to your bot via Microsoft Teams again and step through the code so you understand what’s happening.
  2. Fiddle with it: Try modifying the bot to return something else to the user – e.g. call to reply with a random Chuck Norris joke.
  3. Read more: Read more about utilizing cards here and capabilities of Bot Framework SDK here.
  4. Windows Azure: Deploy your Bot to Windows Azure. Once that’s done, update the bot registration in Bot Framework to have the URL of your Windows Azure website or cloud-service (depending on what you chose).
