B2B Collaboration / User Management

Question

Hello, I am a Global Admin for this tenant. Today, I attempted to use the Bulk Invite feature to add guest users. The batch partially succeeded, but then my tenant was seemingly throttled/blocked mid-process. Now, all subsequent manual and bulk invites are failing with an 'Insufficient privileges' error, despite my Global Admin role. Please check if our tenant's B2B invitation capabilities have been automatically restricted by your anti-spam filters and lift the block immediately so we can finish onboarding our users.
