Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Lianqi,
If the issue persists, I highly recommend you submit a reinstatement form:
https://www.microsoft.com/concern/AccountReinstatement?SilentAuth=1&wa=wsignin1.0
Because this forum is just a user-to-user forum, no-one here has any account access, you will need to contact Microsoft Support directly to ask them to try to recover your account:
Go to Contact - Microsoft Support: Contact - Microsoft Support
- In the search box, type "account issues" and press Enter.
- Scroll down and select the "Contact Support" or "Sign in to contact support" option. You can sign in using any other accessible email address you have.
- For "Product and services", select Microsoft 365 and Office.
- For "Category", select Manage my profile information.
- You should then see the option to "Chat with a support agent in your web browser".
