Outlook mailbox appears to be corrupted.

Question

All incoming emails from trusted sources show the same subject line (Matt Atkin George10!) The preview text is identical across all emails.

When you open any email it has the same phishing text, even drafts are affected.

This is not spam, its affecting all legitimate senders.

I need this escalated for a mailbox restore and a recovery of original email content.

This is urgent as I cant read my emails.

There were multiple rules set up, in Hebrew which I have deleted, I have changed my password multiple times.

If so, then you are correct that you will probably need Microsoft Support to clean it up entirely.

Hi! This does suggest the account may have been compromised. Since you already found suspicious rules, I recommend reviewing your Microsoft account Security page and Recent activity, confirming your security info is still yours, signing out of all sessions, and removing any unknown app permissions. Then, in Outlook.com on the web, check Rules, Forwarding, and Automatic replies for anything you did not create. Also run a full malware scan on the devices that had access to the account. Finally, check Deleted Items and Recoverable Items to see whether original copies of the affected messages can still be restored, because that is the recovery method Microsoft documents publicly for Outlook.com mail.
