Hi @Super Boss

We appreciate you contacting us offline and shared tenant details over email.

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. As you've mentioned, you can now access it successfully.

Hi @Super Boss

This usually means that your Azure AD tenant has been flagged by Microsoft as a possible security risk or unusual activity. I recommend that you submit a support ticket to Microsoft Support and provide details of your tenant to help the support team unblock your tenant.

Hope this helps.

Cannot add guest users to our Teams. It always shows the below message.

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

Raising many support requests but they cannot help. This is what I get from the MS support team.

Hi Son, I have feedback from internal team, and we will escalate this to our escalation team. Thank you for your patience. Regards,

Think of switch to other products :(
