After the initial set up, you may still need to reauthorize Zoom Scheduler to maintain calendar connectivity, especially if changes in your email service (Google or Office 365) security settings caused your access token to expire. Reauthorization grants Zoom Scheduler read/write access to your email service, which is essential for it to function properly. 

If your Zoom Scheduler has been disconnected or has stopped working, you will either receive an email from scheduler-noreply@zoom.us with subject [Zoom Scheduler] Calendar account connection issue or notice a yellow icon with an exclamation point next to your name within the team event host listing signifying that your Zoom Scheduler needs to be reauthorized.

When this happens, follow these steps to resolve the issue.

Option 1: Use the Reauthorize link from the email sent to your account.

The email must be from scheduler-noreply@zoom.us with the subject [Zoom Scheduler] Calendar account connection issue. 

From the email, click the Reauthorize button. This will prompt you to log in to your calendar service to grant Zoom access again to continue using Zoom Scheduler.

Option 2:

1. Sign in to your Zoom account on the Zoom web portal.
2. In the left navigation menu, click Scheduler.
3. In the top-right corner, click Settings.
4. Click the Accounts tab.
5. Click Reauthorize.
   This will prompt you to log in to your calendar service to grant Zoom access again to continue using Zoom Scheduler.
