Troubleshooting OneDrive Integrations

Most OneDrive connection failures trace to one of two causes: the account used for the connection lacks permission to the OneDrive resources you expect to reach, or the authentication flow is rejected because the domain or email address fails Microsoft's requirements.

Incorrect OneDrive Access Permissions

When connecting to OneDrive, Files.com can only access the OneDrive resources granted to the credentials used for the connection.

Confirm that the OneDrive account authenticating the Remote Server connection has been granted permission to the required resources. Log in directly to OneDrive with the same account and verify that you can reach those resources. If you cannot, contact your OneDrive administrator.

Authentication Issues

For authentication to succeed, your OneDrive must use a verified domain, as Microsoft requires. Microsoft Learn documents the verification process: https://learn.microsoft.com/en-us/entra/identity/users/domains-manage. Verify your OneDrive domain before attempting to authenticate.

The user account used to authenticate must have a valid email address associated with the verified domain. By default, the domain of the email address matches the verified domain, though Microsoft Entra can be configured to allow email addresses with domains that differ from the verified domain.
