Adaptive Cards for Outlook Actionable Messages using Power Automate | Power Platform

Let’s take a look at how you can design Adaptive Cards for Outlook and get response from Outlook users to process using Power Automate.


Let’s say I wanted to send an Adaptive Card to an Outlook user on their Email and ask some comment, example – A descriptive feedback and read their response back and send them a confirmation Adaptive Card.

In this post, I’ll simply read the Response in the Flow and send a Confirmation-like Adaptive Card so that you can then further decide to take required action for it based on your use case.

Adaptive Cards Designer – Initial Card Layout

You can logon to i.e. the Adaptive Card designer and start building your card. Below are the high-level steps:

  1. Once you are in the Adaptive Cards Designer, make sure you select the host app as “Outlook Actionable Messages

    You’ll see a sample already created for you which you can start working off of –

  2. Since I want to start from the beginning, I’ll select New Card option as shown below

  3. Now, I’ll start to design my card with the use of some TextBlock, an Input.Text to capture a response. In your case, you can choose the type of input(s) you want. (I’m trying to keep it simple for now 😊)
    These controls works like a drag-and-drop behavior, just drop whatever you need.

    So, I did the following, I added a TextBlock to add the title I want to show on the card and a Multi-line Input.Text to capture a response of the user I’ll send the card to in their Email.

  4. For the Input.Text, I’ve added an id ‘answer‘. We’ll need this when we capture responses back.
    Also, to make the Input.Text control as multi-line, Multi-Line option should be selected as I did below

  5. At this point, our Adaptive Card’s layout is ready. Before we proceed we must first, create a Flow that will capture an HTTP Response and then we’ll come back here.

Flow to Capture Response

Adaptive Cards for Outlook Actionable Messages work off of the HTTP mechanism and that’s why you need a URL where you can capture the responses and send back a confirmation response back.

Let’s call this Flow as “Accept Feedback Response

  1. To do so, first create a Flow that Accepts an HTTP Request. You can refer my other post in order to understand how you can capture HTTP Responses – Accept HTTP Requests in a Flow and send Response back | Power Automate
    Once once you save a Flow that has a trigger of HTTP Response, you’ll get a URL generated, copy it.

  2. Next, I’ll enter the schema by clicking on Use sample payload to generate schema button on the first step above and enter the following schema since I know that’s what is to be expected from the User when they fill in the Text and submit back.

  3. Once you click OK, your schema will look like this.

  4. Collect the result of the above trigger in the Compose so that you can save the Flow with at least 1 Action. (We’ll come back to it later)

  5. Next up, we will also need to setup a response Adaptive Card. This is something that the users will see when they Submit their responses.

  6. It is mandatory to send the response back to the caller i.e. the Outlook in this case. Hence, we’ll send a Response back using Response action in HTTP and send the status code as 200 and header CARD-UPDATE-IN-BODY as true.
    The Body will have the Adaptive Card which we created in step #5 above i.e. the Adaptive Card we have to send as confirmation.

    Here are the details of Refreshing Cards when you send back a response to the client (Outlook user in this case):

Complete your Adaptive Card – Add Action

Once your Flow to capture the response is ready, let’s complete the Adaptive Card to add an Action to the same.

  1. Select the card body, you’ll see a button to Add an action

    You’ll need to select Action.Http

  2. Once you select the Action.Http type of Action, look at the Element Properties, you’ll need to enter the URL we got from the Flow we created to capture responses above.

    Here why we chose Action.Http –
  3. Next, set the title of the Action (it appears as a button). I’ll name it Submit.
    Also, select what kind of Method is to be used for the HTTP Request.

  4. Now, since you’ve selected POST method, you will need to pass the Body. This will be the response which the user will send and which the Flow above will read it as a Response to process the information further.
    Once you select POST, a Body element property will be added where you need to enter the schema and what ID of the element that information belongs to

  5. Remember, the ID for the Input.Text was set as “answer”, we’ll put that here and then it’s Value property. These values should be enclosed in double curly brackets {{ }}.

  6. And also, you’ll need to pass along the Header for Authorization. Read this post by Microsoft –
    Add Header as shown below

    Now, as mentioned in the above post, we need to pass the property as Authorization header and leave it blank and Content-Type as application/json

  7. Once all this is done, it’ll look like below in the card payload for the Action.Http part.

  8. Now copy the entire Payload from the Editor and we’ll create a new Flow that will be used to send the Adaptive Card to the user.

Flow to Send the Adaptive Card in Email

I’m creating a Flow here which will be used to send the Adaptive Card. To keep it simple, I’m just triggering it using a button on-demand. Your use-case will vary.

Let’s call this Flow as “Send Feedback Request

  1. Wherever you need to create the Adaptive Card, you’ll need to paste the entire Payload copied from the step above in a Compose step

  2. I’ll add a step to send an Email directly using Send Email and make sure you enable the </> part for the body.

    Make sure the Outputs of the Compose we pasted above in Step #2 are enclosed in
    <script type="application/adaptivecard+json">


Let’s look at how this will turn out!!

  1. Let me just Run the Flow as is so that the Adaptive Card is generated and sent to the user I intend to in the Email.
  2. They’ll receive an email like this

  3. And the user will submit the answer in the text box and submit.

  4. Once they submit, the Accept Feedback Response Flow we created will be triggered

  5. And the response is available to be read and processed further in the Compose step we created to collect it with the defined schema.

  6. The Adaptive Card we had created to send back as confirmation (which looks as below) will be sent

  7. Once the user submits, they’ll get the below Adaptive Card as a confirmation that their feedback has been taken.

And that’s how you can make your Adaptive Cards to function with Outlook!! Hope this was helpful.

Summarizing D365 App For Outlook Setup in 3 steps with Exchange Online mailbox

Remember, there are a lot of considerations for security and synchronization. The above setup is recommended for all first time Outlook and Dynamics users. While all this, I would like to summarize the steps for all you first time users!

Here’s a crash course guide to setting up D365 App For Outlook for new on-boarders.

Part 1 – Outlook License

  1. So, you can have any of these licenses which has Outlook service included. Be it Enterprise E3, E5 etc. Basically, you need an Exchange Online mailbox. Also make sure the license is assigned to the user and Mailbox is created as below.

Part 2 – Enable Server Side Synchronization

Once Mailbox is setup for the User. Now, let’s go the D365 For enabling Server Side Synchronization on the user’s mailbox. Remember, you must be a Global Administrator to Approve the Mailboxes.

  1. Go to Settings >Email Configuration > Mailboxes. Open Mailbox you want to enable SSS for.
  2. Then, click on Approve.
  3. Then, click Test & Enable Mailbox from the ribbon.
  4. This is important, if you have multiple instances like Production, Sandboxes etc. Choose if you want to only enable it for the current organization and not else where, select the checkbox.
  5. The Mailbox in D365 will complete testing in a few minutes and you should see the status of the same  as Success if everything went well.

Part 3- Enable D365 App For Outlook

Now, once Server Side Synchronization is enabled, you’ll need to go to Dynamics 365 App For Outlook in Settings.

If you don’t see the above in your SiteMap, refer this post for the details and the shortcut-

Now, in my case, I had selected to enable this feature for anyone who has already been enabled with Server Side Sync to also be enabled for D365 App For Outlook.

Hence, when I opened the App, I could already see my being added to the App!!


Else, you’ll need to add other users explicitly by selecting them and clicking on Add App To Outlook button on the view shown above.


You’ll see the Dynamics icon that denotes the D365 App For Outlook, you can click on it and the D365 App For Outlook is ready to be used for that selected item.

and the app will show up in the pane next to it.


For detailed information on Support Matrix of the D365 App For Outlook, refer this –

Here is also a YouTube video summarizing the same: 

Hope this summarizes the setup well!

D365 For Outlook 2016: There is a Problem communication with the Microsoft Dynamics CRM server for D365 v9

One of the recent and most frequent issues faced while upgrade is that of the existing Dynamics 365 For Outlook 2016 setup which doesn’t connect to D365 v9.

Right after the environment upgrades to v9, D365 For Outlook’s older version doesn’t connect.

But that’s not the end of the story, obviously, there’s is an upgrade. So let’s see how to go about this process and why this happens.


When you’re trying to re-enter credentials or connect to D365 v9 from the existing D365 For Outlook version, you see this error


The reason is that D365 version 9 required TLS 1.2. Detailed explanation of which you can find here –

Version Upgrade

You can either choose to upgrade to D365 For Outlook v8.2.2.137 which you can download from here –

Or, if you don’t have any pre-installed version, you can also directly setup D365 For Outlook –

Make sure you have upgraded your D365 to v9 first. I’ve posted a related blog regarding this in the past and you can refer it here –


Hope this helps! 🙂
