Hi @Jagadeesh Yarra,
Thank you for sharing your issue on Microsoft Q&A.
This email is triggered when you haven't accessed or signed in to your Azure tenant for the past 200 days. As per Microsoft data retention policy, if a tenant remains inactive without any sign-in activity, the account gets disabled, and customer data deleted.
If you don’t log in to your Azure tenant via https://portal.azure.com/ within the specified time frame, it may be permanently deleted. Inactivity can trigger Microsoft’s process to remove unused tenants. Once a tenant is marked as inactive, the OMS commerce system enforces a login block. During this time, any sign-in attempts will result in the following error: "AADSTS5000225: This tenant has been blocked due to inactivity."
Twenty days after the login block is applied, the tenant will be permanently deleted.
For more details about inaccessible tenant, please refer: Tenant inaccessible due to inactivity
To prevent this, simply log in to your Azure tenant via https://portal.azure.com/. Check whether any subscriptions are present that may need attention. If there are no active subscriptions, no further action is required — your login itself counts as activity and will prevent the tenant from being blocked.
