# Microsoft Outlook
> Microsoft Outlook is a personal information manager software system from Microsoft, available as a part of the Microsoft Office suite. Though primarily an email client, Outlook also includes such functions as calendaring, task managing, contact managing, note-taking, journal logging and web browsing.
## Creating a Microsoft Outlook connection
Create the connection by using one of the following methods:
* [OAuth](#using-oauth)
* [App Registration](#using-app-registration)
### Using OAuth
#### Creating your connection
1. In the Blink platform, navigate to the **Connections** page > **Add connection**. A New Connection dialog box opens displaying icons of external service providers available.
2. Select the **Microsoft Outlook** icon. A dialog box with name of the connection and connection methods appear.
3. (Optional) Edit the name of the connection. At a later stage you cannot edit the name.
4. Click **Outlook** to authenticate using OAuth.
5. Sign in using your credentials.
Need admin approval? please refer to the [Need Admin
Approval](/docs/integrations/microsoft-outlook/admin-approval) guide.
### Using App Registration
To create the connection you need:
* A Client ID
* A Client Secret
* A Tenant ID
#### Obtaining the credentials
1. Log into the [Azure Portal](https://portal.azure.com/#home).
2. Go to the *Microsoft Entra ID* resource.
3. In the left-hand menu, click **App registrations**.
4. Create a new application registration or click on one of your existing applications.
5. In the left-hand menu, click **API permissions**.
6. Click **Add a permission** and select **Microsoft Graph**.
7. Choose **Application permissions** and mark the permissions you wish to add.
To support all Blink actions, these are the required **application** permissions:
As a best practice, request the **least privileged permissions** that your app
needs in order to access data and function correctly. Requesting permissions
with more than the necessary privileges is poor security practice, which may
cause users to refrain from consenting and affect your app's usage. For
additional information, refer to [Microsoft Graph
permissions](https://learn.microsoft.com/en-us/graph/permissions-reference).
| Least privileged permissions | Higher privileged permissions |
| ---------------------------- | ----------------------------- |
| Mail.ReadWrite | Mail.ReadWrite |
| MailboxSettings.ReadWrite | Mail.Read |
| Calendars.ReadWrite | Calendars.ReadWrite |
| Mail.ReadBasic.All | Calendars.Read |
| Mail.Read | |
| MailboxSettings.Read | |
| Mail.Send | |
| Calendars.ReadBasic | |
| Calendars.Read | |
8. Click **Add permissions** to save the changes.
9. Click **Grant admin consent for ``** on the API permissions page. **Only admins can grant consent**.
10. Confirm that the added permissions are now verified.
11. Navigate to **Overview** and Copy your **client ID** and **tenant ID**.
12. Create a new **client secret**.
13. Copy the **secret value**.
