These are some of the top questions we receive about using the One-Click setup for the Outlook mailer.

#### Why has my site stopped sending emails?

This issue usually arises due to an expired Outlook connection or an expired WP Mail SMTP license.

To address this, first, ensure you have an active subscription plan with WP Mail SMTP. If your license has expired, you’ll need to [renew it](https://wpmailsmtp.com/docs/how-to-renew-your-wp-mail-smtp-license/).

Then, navigate to **WP Mail SMTP » Settings** and click on the **Reconnect** button. This action will renew your connection with Microsoft, ensuring uninterrupted email delivery.

#### Will I need to reconnect if I change my credentials?

Yes. Your account will be invalidated if you change your password. To fix this issue, you’ll need to re-authorize your WP Mail SMTP connection.

For this, go to your WP Mail SMTP settings page and scroll down to the 365 / Outlook mailer section. Next, you’ll need to disconnect your account. To do so, click the **Remove OAuth Connection** button in the **Authorization** section.

![Remove OAuth connection](https://wpmailsmtp.com/wp-content/uploads/2024/12/remove-oauth-connection.png "remove-oauth-connection-2 - WP Mail SMTP")After that, you’ll need to reconnect your account by clicking the **Sign in with Microsoft** button.

#### Can I use the 365 / Outlook mailer if I have 2-factor authentication (2FA) enabled on my Microsoft account?

It shouldn’t be an issue if you already have 2FA / MFA enabled before completing the steps in this tutorial.

However, if you enabled 2FA / MFA after setting up the Outlook mailer on your website, you’ll need to re-authorize your Microsoft account. Please see the authorization section of this guide to learn how to do it.

That’s it! You’ve successfully set up the Outlook mailer with the One-Click Setup feature in WP Mail SMTP.
