Admins can use their Single Sign-On (SSO) configuration to enable and authorize the calendar and contacts integration for all users by collecting access tokens for Outlook. End users are prompted to authorize this integration and have the calendar and contact details automatically populated into their Zoom desktop client. The calendar events are shown in the Zoom meeting list and the contact list is shown in the Zoom contact directory.

To configure this integration, the account must have Single Sign-On configured and their identity provider must be federated with Azure Active Directory.

Note: See the account-level settings in the web portal to learn more about calendar and contacts integration.

How to enable Ask users to integrate Office 365 with SSO credentials

4. Under Integrations, click the Ask users to integrate Office 365 calendar when signing in with SSO credentials toggle to enable or disable it.
   • Select Ask users the first time they sign in if you want Zoom to redirect your users to the Office 365 OAuth URL they sign in using SSO the first time. If the users don't accept the OAuth request or an error occurs, users can only set up calendar and contacts integration manually.

   Note: If the option is grayed out, it has been locked at the account level and needs to be changed at that level.
6. (Optional) If you want to make this setting mandatory for all users in the group, click the lock icon , and then click Lock to confirm the setting.

How to grant permission to use the Zoom app in Microsoft Azure

An Office 365 admin needs to grant permission for the Zoom app to integrate users' calendars and contacts from Azure. You can allow the integration by granting permission to all applications or by granting to the Zoom app only.

How Office 365 admin grant permission to all apps

1. Sign in to the Azure portal with a role that allows granting admin consent.
2. Select Azure Active Directory then Enterprise applications.
3. Under the User consent for applications section, select Allow user consent for apps.
   Note: This will take about 30 minutes to propagate.

How Office 365 admin grant permission to the Zoom apps only

What to do if Office 365 admin did not grant permissions to use the Zoom app in Azure

One known issue with the calendar and contacts integration is users receiving an error Need admin approval at the time of sign in. This occurs because the user's Office 365 admin account has disabled the option Users can consent to apps accessing company data on their behalf in Azure.
