3. On the registration page, fill in the application settings: name and account type.

{% hint style="success" %}
It is recommended to select Accounts in any organisational directory, as integration with NovaTalks works only with corporate mail.
{% endhint %}

4. Click **Register** and the application will be created.

## Creating Client Secret

In the Certificates & Secrets section:

1. Click **New client secret**
2. Enter the description and validity period.
3. Click Add - the client secret will be generated.

{% hint style="warning" %}
Save the Secret ID value right away - you won't be able to see it after the page refreshes.\
You will need to specify this parameter when creating an Inbox in NovaTalks (see more details in [Email](/en/get-started/settings/inboxes/email.md)).
{% endhint %}

<figure><img src="/files/U5NiTR2gi6lQSsCfDLgb" alt=""><figcaption></figcaption></figure>

After receiving the Client ID and Client Secret, create an Inbox to connect your Microsoft account to NovaTalks (see more - [Email](/en/get-started/settings/inboxes/email.md)).

To complete the registration, add the Redirect URI, received after creating the Email channel. This address will be used to redirect the user back to NovaTalks after authentication.
