Hello @Romain Coquette
Thank you for posting your query on Microsoft Q&A.
The error message you encountered indicates that your tenant has been inactive for over 200 days past the billing cycle, triggering Microsoft’s effort to remove inactive tenants. When a tenant remains inactive for this period, the OMS commerce system imposes a login block (AADSTS5000225). Twenty days after the login block is applied, the tenant is permanently deleted.
Tenant inaccessible due to inactivity
If you plan to unblock your inactive tenant, it’s essential that it has been blocked for less than 20 days. After the 20-day period, the tenant is permanently deleted and cannot be recovered.
If it has been less than 20 days since the block, please provide the following details for further assistance:
- Tenant ID
- Error Code
- Correlation ID from the recent failure
- Timestamp from the recent failure
- Business impact and justification for restoring the tenant, and an explanation of the impact if the tenant cannot be restored
Note: If it's a test tenant, please re-create a new tenant for testing purposes.
