You might wonder what happens to the data when your trial tenant expires.
Trials live in the following phases:
Subscription is then deprovisioned
During ‘Active’ and ‘In Grace’, the service is fully functional. Enrollment works, login’s work etc. Once the subscription hits the ‘Disabled’ state, nothing works anymore. It’s basically the final 30 days where the subscription data can be recovered . Once the subscription is deprovisioned, the data isn’t recoverable anymore.
Once the final subscription (of any service like Office365 or Intune) is deprovisioned from a tenant, then the countdown starts to where that tenant is then deleted from Windows Azure Active Directory (WAAD). The default used to be 75 days but could change to free-up tenant names sooner.
