Unknown person(s) sharing files with my OneDrive

Hello Jamie Heitler,

Thank you for posting in Microsoft Q&A forum.

I understand you’re concerned about random people sharing suspicious files with your OneDrive account.

Here are steps you can take to stop this and secure your account:

1. Do not open or download unknown files: continue flagging them as malware.
2. Remove shared links:
   • Go to https://onedrive.live.com.
   • Select Shared > Shared with me, then remove any suspicious shared items.
3. Block the sender:
   • In OneDrive, click the file owner’s name and choose Block to prevent future shares.
4. Strengthen account security:

• You’ve already changed your password and enabled 2FA, which is great.
  • Review your https://account.microsoft.com/security and check Recent activity for unauthorized access.

1. Report phishing:
   • Use https://www.microsoft.com/en-us/wdsi/support/report-unsafe-site to report suspicious files or links.
2. Check connected apps and devices:
   • Remove any unfamiliar apps from https://account.live.com/consent/Manage.
   • Ensure only trusted devices are listed under Devices in your account.

If the issue persists, contact https://support.microsoft.com/contactus for further assistance.

Let me know how it goes.
