I’ve tried to recover your lost messages. I was able to recover some e-mails and have moved them to your Inbox. Although, I can’t guarantee that the recovered messages will include all the ones that you are looking for.
If you think that your account may have been compromised, then I recommend that you ensure your account’s security. Please take a look at MSFT Scott H’s Solution Article “What to do if you think your account has been stolen” as it provides helpful tips in keeping your account secure.
