Zoom Scheduler and Calendars Reauthorization (Outlook / Office 365)

If your Zoom calendar integration stops syncing with Outlook, you may need to reauthorize the connection. This can happen after a password change, a system update, or when your authorization token expires. This article walks you through three ways to get things back on track.

Method 1: Use the Email Notification

Zoom will automatically send a notification email when your calendar connection needs attention.

1. Look for an email from scheduler-noreply@zoom.us with the subject line: [Zoom Scheduler] Calendar account connection issue
2. Click the Reauthorize button in the email.

   

3. You will be prompted to sign in to your Outlook/Office 365 account and grant Zoom access again.
4. After completing the sign-in, your calendar connection will be restored.

Method 2: Reauthorize via the Zoom Web Portal

If you did not receive an email notification, you can reauthorize manually through the Zoom web portal.

1. Sign in to your Zoom account at https://dartmouth.zoom.us.
2. In the left navigation menu, click Scheduler.
3. In the bottom-left corner of the Scheduler page, click Settings (tiny gear icon).
4. Accounts Tab
5. Will prompt to Reauthorize or click Add an account.

   

6. Sign in to your Outlook/Office 365 account when prompted and grant the requested permissions.

Method 3: Reauthorize Calendar Service

You can also reauthorize directly within the Zoom desktop application.

1. Sign in to your Zoom account at https://dartmouth.zoom.us.
2. In the left pane, click Settings.
3. Scroll to Mail & Calendar tab at the top.
4. Select Office 365 from the list of calendar options and click Next.
5. Click Authorize and confirm that the Authorize with OAuth 2.0 checkbox is selected.

   

6. Enter your Office 365 email address and password when prompted, then click Accept to complete the authorization.
