Invitations are blocked for this directory due to suspicious activity. Please contact Microsoft support for help

Question

Hello Microsoft Support,

Affected tenant ID: PII

We are experiencing a critical issue with our Microsoft Entra ID tenant. All guest invitations in the tenant are failing with the following error:

error": {
    "code": "Forbidden",
    "message": "Invitations are blocked for this directory due to suspicious activity. Please contact Microsoft support for help."
}

Context of Issue:

We are now changing the way we store users in our applications, we have provisioned a new tenant and are migrating our legitimate existing user base from the parent organization's tenant into this new tenant. All users being invited are real users - this is a one-time migration operation, not spam or abuse.

Please review and remove the "suspicious activity" block on the tenant.
