Hi, I'm John! I will help you with this.
If you’d like, please let me know whether you can sign in to OneDrive normally and what the sender’s email domain is (you can mask part of it).
Microsoft does send legitimate OneDrive storage warning emails, but there are also phishing emails that look very convincing.
To stay safe, here’s how to tell the difference:
- Don’t click any links in the email for now.
- Check the sender’s email address carefully. Official Microsoft emails usually end with @microsoft.com (not random domains or misspellings).
- Sign in to OneDrive directly to https://onedrive.live.com in your browser (not link through the email). If there’s a real issue, you’ll see the warning after you sign in.
- In Outlook, look under Settings > Storage or OneDrive storage info to confirm if your account is over quota or inactive.
IMPORTANT: If the email is asking for urgent action, threatening immediate deletion, or asking you to “verify” your account, that’s a red flag and likely a scam.
I really hope this information is helpful! Let me know if you have any further questions or concerns.
Regards,
John J.D.
