"Invitations are blocked for this directory due to suspicious activity" for a free tier tenant

Question

Here is the thing, I am testing with my developers tenant and making attempt to add 150 guest user to a Teams channel.

The moment I hit the 100 mark I could no longer add anyone.

I have also tried to add from the Entra portal it did not work out.

Kindly help with this issue.

Hi @Ayodele

Thank you for posting your query on Microsoft Q&A.

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

To re-enable invitations, I need a few details from you to coordinate with my engineering team. Please share the following information via email to azcommunity [at] microsoft [dot] com with the subject line "ATTN: Navya", as it contains PII.

1. Tenant ID, display name, domain name of both resource tenant and home tenant.
2. What is the business justification and scenario they will be using invitations for?

Once I receive these details, I'll work with the engineering team to enable invitations in your tenant. I look forward to your response.

Thanks,

Navya.
