(aka.ms/TSP_Achievement_Code_Enroll...) restricted across all accounts unable to enroll Class Admin

The enrollment form at aka.ms/TSP_Achievement_Code_Enrollment returns 'restricted access' for me. I have tried signing in with all three of the following:

1. email address removed for privacy reasons (work / Entra tenant, Partner Center account)

2. email address removed for privacy reasons (consumer MSA with Learn profile)

3. email address removed for privacy reasons (new outlook.com alias, per the Account Enrollment Guide)

Same restriction on all three, so this looks like a tenant or program-level block rather than an account issue.

I also have an open support case (#715-123160) regarding an earlier fraud-detection block on our tenant, which may be related. Microsoft Support has twice advised me to post here.

Could someone please:

Escalate for a manual unblock if there is a tenant-level restriction.

This is the only thing blocking us from issuing Achievement Codes for our May 2026 intake. Happy to share more details via DM.

Thank you,
