I tried adding around 200 users in bulk last week but the operation failed mid-way with the "Request was unsuccessful. Details: Invitations are blocked for this directory due to suspicious activity. Please contact Microsoft support for help." error message.

    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 :(
