Zoom + Office 365: Graph API and Domain Association Errors

Hi community,

We’re trying to integrate Zoom with Office 365 for calendar and contacts sync. However, we’re running into these errors:

• “Your account may not be compatible with the Microsoft Graph API”

• “Zoom association domain does not match O365 verification domain”

This happens when selecting API Graph as the authorization method and using OAuth 2.0.

Important clarification:
We are using a Microsoft 365 account (corporate tenant) – not a personal Outlook.com or Hotmail account. The domain is verified and active in Azure AD.

What we tested:

• Integration works perfectly in a test tenant (Microsoft 365 tenant with minimal restrictions).

• The issue only occurs in the production tenant .

• Zoom is registered as an Enterprise Application in Azure AD.

• Admin consent has not been explicitly granted for Microsoft Graph API permissions.

Question to the community:
Has anyone experienced a similar issue with Office 365 integration?
What settings should we review in the Microsoft 365 Admin Center or Azure AD to allow Zoom to:

1. Access the Microsoft Graph API for calendars and contacts?

2. Pass the domain association check between Zoom and O365?
