Observed behavior

Contact Microsoft 365 Support for Backend Log Review

The most effective way to resolve complex multi-tenant synchronization and authentication errors is to have Microsoft investigate the backend logs.

Intermittent errors often result from directory synchronization, authentication latency, connectivity, or account-recognition problems between the regional and central tenants.

Because tenant-level authentication logs are not fully exposed to end users or regional administrators, a Microsoft 365 administrator must escalate the issue to Microsoft Support.

1
Log into the Admin Center

Go to the Microsoft 365 admin center (admin.microsoft.com) and log in using an account with administrator privileges.

2
Navigate to Support

Click on the 'Support' icon in the lower-right corner or select 'Help & support' from the left navigation pane.

3
Open a Support Request

Briefly describe the multi-tenant form permission issue and submit a formal support request so the backend team can review the relevant sync and authentication logs.

Frequently Asked Questions

Why do regional users get access denied errors on central tenant forms?

This occurs because the form requires authentication in the central tenant. If there are delays or failures in user directory synchronization between the regional and central tenants, the central tenant fails to recognize the user's cross-tenant identity.

Will setting the Microsoft Form to 'Anyone can respond' fix the issue?

Yes, changing the permission to 'Anyone can respond' will bypass the authentication requirement, allowing all users to access the form. However, it will no longer automatically record the respondents' names or email addresses.

Can an end user fix the multi-tenant synchronization error on their own?

No, directory synchronization and cross-tenant authentication are managed at the organizational level. A Microsoft 365 administrator must investigate or contact Microsoft support to resolve backend configuration or sync issues.
