If you don't plan to reactivate your tenant:

• The tenant is deleted after 20 days of being inaccessible due to inactivity and it isn't recoverable.
• Review Microsoft's data protection policies, here.

Application owners/developers

• Minimize the number of authentication requests sent to this deactivated tenant until the tenant is reactivated.
• Refrain from submitting another assistance request. You are contacted once that a decision is made.
