My mail account has been hacked, the inbox is flooded with malware mails and many of my mails have been removed. How can I restore the mailbox to its old state?

I have looked at the deleted mail folder, looking for restoring mails, but five years of mails are gone somehow.

    Hi Daniel Spahr

    I understand how alarming it is to see your account compromised and important emails missing.

    To help me guide you better, could you please clarify:

    • Are you still able to sign in to your Outlook.com account?
    • Do you see any unknown forwarding rules or email rules set up?

    Meanwhile, please try the following:

    1, Secure your account (if you still have access)

    For reference, you can see:

    2, Check for hidden mail rules

    Attackers often create rules to delete or move emails:

    • In Outlook.com, go to “Settings” > “Mail” > “Rules”
    • Remove anything suspicious

    Also check: “Settings” > “Mail” > “Forwarding” (disable if enabled unexpectedly)

    3, Try to recover recently deleted items

    Even if Deleted Items is empty:

    • Open “Deleted Items” folder
    • Click “Recover items deleted from this folder” at the top

    Note: This only restores emails that are still within Microsoft’s retention window. Older emails (like several years ago) may no longer be recoverable.

    If emails were permanently deleted and are outside the retention period, they cannot be restored by support or any tool. Thank you for your understanding.
