# Microsoft 365 Calendar Integration Setup (/docs/integrations/microsoft-calendar)





## Grant Admin Consent [#grant-admin-consent]

A Microsoft 365 **Global Administrator** must grant tenant-wide consent for Backdrop to access your organization's calendar data.

### 1. Open the admin consent link [#1-open-the-admin-consent-link]

Sign in as an admin and click the link below to start the install:

[**Install Backdrop Application**](https://login.microsoftonline.com/common/adminconsent?client_id=29c0d58b-aeae-4d67-956a-066e8d2a471b\&redirect_uri=https://getbackdrop.ai)

<Accordions type="single">
  <Accordion title="Need to install on a specific tenant?">
    The link above uses `common`, which lets Microsoft pick the tenant based on the signed-in admin. To target a specific tenant, use this URL instead and replace `<TENANT_ID>` with your **Tenant ID**:

    ```
    https://login.microsoftonline.com/<TENANT_ID>/adminconsent?client_id=29c0d58b-aeae-4d67-956a-066e8d2a471b&redirect_uri=https://getbackdrop.ai
    ```

    You can find your Tenant ID in the [Microsoft Entra admin center](https://entra.microsoft.com) under **Overview** → **Tenant ID**.
  </Accordion>
</Accordions>

### 2. Approve the requested permissions [#2-approve-the-requested-permissions]

1. Sign in with a **Global Administrator** account for the tenant you want to install Backdrop on.
2. Review the permissions Backdrop is requesting.
3. Click **Accept** to grant tenant-wide admin consent.

After approval you will be redirected to `https://getbackdrop.ai`. The integration is now active for your organization.

## Finish Backdrop Configuration [#finish-backdrop-configuration]

Notify your sales rep once consent has been granted so they can complete the setup on Backdrop's side.
