Using Classic Outlook on Windows for personal email, calendar, and contact management
The error AADSTS5000225 in the screenshot means the Azure AD tenant linked to the Microsoft account was blocked due to inactivity, not that the personal Outlook/Microsoft account itself is blocked.
To try to regain access to the Azure portal:
- If the tenant became inactive recently (within about 20 days):
- A tenant administrator must contact Microsoft support and request tenant reactivation. Administrators can use the global support phone numbers listed in the Azure tenant inactivity guidance. While the case is open, do not submit multiple assistance requests, as that can delay the response.
- Try signing in directly with the tenant identifier:
- Use
https://portal.azure.com/<TenantId>orhttps://portal.azure.com/<TenantName>.onmicrosoft.com(replace with the tenant’s actual ID or name) to see if the portal allows access and lets an admin open a support ticket.
- Use
- If the tenant has already been inactive too long:
- After the inactivity window, the tenant is deleted and cannot be reactivated. In that case, create a new tenant from Entra ID:
- Go to
https://entra.microsoft.com/and sign in. - Open Entra ID → Overview → Manage tenants.
- Create a new tenant and note its domain name (for example,
novotenant.onmicrosoft.com). - Then access the Azure portal with
https://portal.azure.com/novotenant.onmicrosoft.comand use this new tenant going forward.
- Go to
- After the inactivity window, the tenant is deleted and cannot be reactivated. In that case, create a new tenant from Entra ID:
If the problem is instead that the Microsoft account itself is locked (for example, when signing in shows that the account was locked for suspicious activity), unlock it first:
- Go to
https://account.microsoft.comand sign in to request a security code. - Use any phone number that can receive SMS (it does not need to be associated with the account) to get the code and complete the unlock.
- If the sign‑in page does not show Next and indicates the account is locked, follow the
aka.mslink shown on that page and submit the account reinstatement form; wait for the email response instead of sending multiple forms.
Once the Microsoft account is unlocked and, if applicable, the tenant is reactivated or a new tenant is created, access to the Azure portal should work again.
