Microsoft Outlook is an email and calendar service from Microsoft 365. It provides business and personal users with email management, scheduling, contact organization, and task tracking.

Through the Microsoft Graph API, Wiresk connects directly to Outlook mailboxes so you can automate email-based workflows.

With this connection, you can watch for new messages, search or retrieve mail, manage attachments, and take actions such as send, reply, forward, move, or delete messages.

Now that you have in hand the Tenant ID, the App ID, and the App Secret, lets create a Microsoft connection.

There are two ways to connect your app to Wiresk:

  • In “My apps” section, where you can manage your connections (select or create your group first to get access to this section, refer to the Group system ).
  • While building your Flow, you can easily establish a connection to your app directly within the Flow builder. This can be done during the setup of either a Trigger or a Method.

In this guide, we will explain how to create a connection in “My apps” section, it is essentially the same as when creating it on-the-go.

  • On your Wiresk’s Dashboard, select your Group.
  • On the left panel, go to “My apps” and select Screenshot 2025 04 08 at 9.58.41 in the morning Microsoft Outlook Mail - Connection
  • Search the app name in the search field or select it in the apps list.

Microsoft Outlook support only OAuth Connection with selected scopes.

  2. Select the OAuth connect tab
  3. Enter your Tenant ID (Mandatory for work or school account) that you saved from How to Get the Tenant ID
  4. Enter your App ID from Get the App ID
  5. Enter your App Secret “value” from How to Get the App Secret
  6. Select Microsoft application for the authorization:
    • Select a single Microsoft app for specific functionality, in our case, Microsoft Graph.
    • Grant access to all Microsoft apps for this connection, allowing broader use of your account (you must set up permissions for each app in your Microsoft Azure Portal).
  7. Click on Authorize button

You can optionally upload a certificate instead of using only a client secret. Certificates provide stronger security for authentication and are recommended for enterprise setups.

You will be redirected to Microsoft “Pick an account” page.

  • Select your connected account or choose another one.

Voila! Your Microsoft Outlook Mail connections is ready. You can now use it to build your Flows.

Now that your app is linked to Wiresk, you’re ready to start building Flows.

Simple steps to create a Flow ↓

Add a Trigger that will start your Flow

Flows can be executed by multiple Triggers, depending on the desired workflow. For example, you could use scheduled Triggers with different recurrence rules alongside a Webhook Trigger for immediate, event-driven runs of the Flow. If you choose to “Run Once“, the Flow will execute using only one Trigger and its sample data.
  • Click on the (+) button to open the Trigger settings side panel.
  • On the settings side panel, click on the “+ Add” button.
Screenshot of the Wiresk side panel titled “Trigger.” The panel shows a section labeled “All Triggers” with a blue “+ Add” button for inserting a new Trigger.
  • On the Trigger selection screen, search your app or select it from the list below the screen.

  • Select your preferred Trigger on the next screen and customize its settings.
As mentioned in “How to connect your app to Wiresk” above, during your Trigger settings, you can create a new connection to your apps at this stage.

Add a Method that will execute a task

The Method will perform a specific task on a particular app or service you’ve connected to Wiresk like get info or send emails.

You can add at least 1 or multiple Methods for complex Flows (a maximum of 255 Methods).
  • On the Flow builder, select the (+) plus button next the Trigger button.
  • Search or scroll down to select the app that will perform a task.
  • Configure the Methods settings, refer to it documentation in our Help Center.

On the right, the panel lists available apps and tools. A search bar is displayed at the top of the panel for filtering apps. Red arrows highlight the empty step placeholder, the search bar, and items in the app list.

Add Wiresk Tools to your Flow

If you want to build a complex Flow, Wiresk offers a selection of tools at your disposal. Refer to Wiresk’s Tools

To add Tools in your Flow, Follow the same step as adding the Methods.

  • On the Flow builder screen, click on the plus button (+) then just click on the “Tool” tab and select the Tool that you want to add.

You can refer to “How to Create a Flow” tutorial for more detailed instructions, including step-by-step guidance on mapping and configuration.

When you configure a Trigger or Method in Wiresk, the settings panel lets you define how data is collected or sent, and the type of values you enter depends on the field.

Field TypeDescriptionExample Value
AuthenticationSecure access credentials that connect Wiresk to the app.Wiresk connection, API Key or OAuth Token
Filters or searchCriteria that narrow which records are retrieved.Search =”QUERY”, Status = “Active” or Type = “Email”
LimitsMaximum number of records to process in one run.Records number = 100
Page number = 1
Field MappingDefines how fields in one step map to another. Can be static or dynamic.Static: Subject = “Report”
Dynamic: Recipient = value from Trigger

Make sure you enter the right values so your Flow works the way you expect and gives the right results. If you need step-by-step details on setting up Microsoft Outlook Mail, check the Triggers and Methods Settings documentation.
