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.

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.

Prerequisite:
You must create a connection to your Microsoft account beforehand.
Connect to your Microsoft Azure Portal to gather information needed to create a connection.
  • On the MS Azure Portal, select Microsoft Entra ID.

  • For the support account types, select “Accounts in any organizational directory (Any Microsoft Entra ID tenant – Multitenant)”.
  • Enter the Redirect URI: Web | https://api.wiresk.com/api/auth/callback
  • Then, click on Register button.

On your Wiresk app overview screen, your App ID and tenant ID are displayed.

  2. Click on add a permission.
  3. Select the Microsoft app that you want to set permissions, in our case choose Microsoft Graph.

  3. Click on Add permissions.

  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.
