It sounds like you're experiencing significant issues with unsolicited files being shared with you on OneDrive, as well as a high volume of junk emails and phishing attempts. Here are some steps you can take to help mitigate these issues:
- Report and Block: While you mentioned that reporting does not seem effective, it's important to continue using the reporting features available in OneDrive and Outlook. Reporting suspicious files and emails helps Microsoft improve their filtering systems.
- Adjust Sharing Settings: Check your OneDrive sharing settings. You can adjust who can share files with you and limit sharing to only those you trust. This can help reduce unsolicited files from unknown sources.
- Use Email Filters: In Outlook, you can set up rules to filter out junk emails. This can help you manage the influx of spam and phishing emails more effectively.
- Enable Two-Factor Authentication: Ensure that you have two-factor authentication enabled for your Microsoft account. This adds an extra layer of security and can help protect your account from unauthorized access.
- Educate Yourself on Phishing: Familiarize yourself with common signs of phishing attempts, such as suspicious links or requests for personal information. This knowledge can help you avoid falling victim to scams.
- Contact Microsoft Support: If you're having persistent issues with specific files or spam, consider reaching out to Microsoft Support directly for assistance. They may be able to provide more tailored solutions or escalate your concerns.
While these steps may not completely eliminate the problem, they can help you manage and reduce the impact of unsolicited files and junk emails.
