+# Error "Change enumeration is not supported for requested tenant" when running a Microsoft Graph delta query
+
+This article provides a solution to an error that occurs when you run a Microsoft Graph delta query.
+
+## Symptoms
+
+When executing a [Microsoft Graph delta query](/graph/delta-query-overview), such as `GET https://graph.microsoft.com/beta/users/delta`, you might receive the following error response:
+
+```output
+'error': {
+'code': 'Request_UnsupportedQuery',
+'message': 'Change enumeration is not supported for requested tenant.',
+'innerError': {
+'request-id': '<request-id>',
+'date': '2020-05-22T13:17:45'
+    }
+}
+```
+
+## Cause
+
+This issue occurs when your tenant is an [Azure Active Directory (AD) B2C](/azure/active-directory-b2c/overview) tenant. Currently, differential or delta queries aren't supported in Azure AD B2C tenants.
+
+## Solution
+
+Run a delta query in a regular Microsoft Entra tenant.
