Hi, I'm John! I will help you with this.
About the persistent draft being credited:
If you haven't tried anything yet, please start by running a full antivirus scan on your computer using Windows Security and any third-party antivirus software you have.
Run a full deep scan using a trusted security tool:
- Download and run Microsoft Safety Scanner here: https://learn.microsoft.com/defender-endpoint/safety-scanner-download
- After running the scan, please restart your PC and monitor whether the issue continues.
To be safe, I recommend the following steps:
Check your account rules and forwarding settings, hackers create rules that automatically forward or delete emails. You can do this in Outlook settings under Mail > Rules and Forwarding. https://support.microsoft.com/office/manage-email-messages-by-using-rules-in-outlook-c24f5dea-9465-4df4-ad17-a50704d66c59
Just to be safe, I’d recommend to sign out everywhere. Visit: https://account.live.com/proofs/manage/additional Scroll down to Sign me out and select "Sign me out".
After signing out everywhere, please monitor if the issue persists in the coming hours.
