Hi Rochanawan S,
Welcome to the Microsoft Q&A forum.
Based on your description, it sounds like your Hotmail account may have been accessed by someone else, which can explain why draft messages are appearing in the Inbox and why older emails are no longer opening. This situation can be stressful, especially when important messages are involved.
To address this, please go through the steps below carefully:
1, Secure the account first
- Start with the recovery and security steps in this guide, including updating your password and securing the account if you still can sign in: How to recover a hacked or compromised Microsoft account.
- Then review your sign-in history and mark anything you do not recognize: What is the Recent activity page?.
- If you suspect someone may still be signed in, you can also force a sign-out across devices: How to sign out of your Microsoft account everywhere.
2, Check and remove suspicious inbox rules
In Outlook.com on the web, check Settings, then Mail, then Rules, and delete any rules you did not create. Reference: Manage email messages by using rules in Outlook.
3, Look for recoverable emails
- Open the Deleted Items folder and check if missing emails are there.
- If Deleted Items is empty, scroll to the top of that folder and select Recover deleted items to see whether any messages are still available for restoration. Please note that emails permanently deleted outside the retention period may not be recoverable. RReference: Recover and restore deleted items in Outlook.
4, Contact Microsoft Support for account review
If older emails still cannot be opened or are missing after securing the account and checking recovery options, this forum does not have the ability to restore mailbox data or review account-level incidents. In that case, you will need to contact Microsoft Support directly so they can review the account status and advise whether any further recovery is possible. Please follow below steps to reach a live chat agent:
- Visit the Microsoft Support contact page: Contact - Microsoft Support
- In the search bar provided on the page, type "Account Recovery" and press Enter.
- Click on the "Get Help" button that appears.
- Scroll down the page until you see and click on the "Contact Support" option.
- When prompted to select your product or service, choose "Other Products".
- For the category, choose "Manage Account Security".
- Look for and click on "Chat with a support agent in your web browser".
- When prompted, provide a valid contact email where Microsoft can reach you regarding your case.
- Explain your situation clearly: Be concise but provide all the relevant details.
Hopefully the steps above help you stabilize the account and determine what can still be recovered.
