Thank you for reaching out to Microsoft Q&A.

As part of its security enhancements, Microsoft has anomaly detection systems in place to identify unusual activity, such as an unusually high number of invitations being sent from a tenant. If such anomalies are detected, the tenant may be temporarily blocked.

To unblock your tenant, please provide a business justification explaining the need for bulk invitations along with requested details via private message only (do not post publicly):

Thank you for your patience

Based on the error message you received it appears that was Invitations are blocked in your tenant due to suspicious activity.

We addressed this by collaborating with our team, who have now unblocked your tenant.

You can check and confirm whether you were able to access the tenant which was blocked.

Hope this helps. Let us know if you have any queries. Happy to assist you further.
