Can't Set up E5 subscription: configurable sandbox

Question

I am registering for developer subscription using the Microsoft 365 Developer Program but I am getting this error: I also try with another number but it's not success. I don't know why

Answer 1

@dxuanquylucas18 As of now, the following may be the reason.

Copilot for Microsoft 365 is not publicly available with Microsoft 365 Developer Program instant sandbox tenants for development and testing. Sandbox tenant availability is currently limited to ISV partners in the TAP

We're sorry to hear that you are having issues joining the developer program. We're also updating the error message to be more specific.

Country-specific outages

We recently had some service issues and many countries were temporarily blocked from joining. This issue has resolved but note the following: Geographic limitations. For technical and security reasons, the Microsoft 365 Developer Program only supports a subset of countries/regions listed here: Microsoft 365 International Availability. We review our supported country list regularly. If you are unable to sign up from your country or region, then it means we do not support it at this time. Membership benefits

While you can still join the developer program, access to the free Microsoft 365 E5 subscription is currently paused for the short-term while we adjust the qualifications for that benefit. To stay apprised of changes, please follow our blog.
