Answer 1

Hi, I'm John! I will help you with this.

Can you check the sender’s email address? Does it look like an official Microsoft domain (e.g. *@microsoft.com)?

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/managestorage 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.

Answer 2

The 80% storage warning is based on total Microsoft cloud storage for the account ("Microsoft storage"), not just what appears in a single place like Outlook or a specific OneDrive view. Microsoft storage includes:

1. OneDrive files and photos
2. Outlook.com pictures and attachments
3. Other files stored by Microsoft apps and services under that personal account

It is possible for:

• The storage banner or email to show 80% used, while
• A specific view (for example, just the mailbox, or just a local OneDrive folder) appears low, because it is not showing all content counted toward the unified quota.

To verify what is really using space and which account is affected:

1. Check the correct Microsoft account
   • Sign in to the Microsoft account that uses the ******@gmail.com address.
   • Ensure no other Microsoft account (for example, an older account or different alias) is signed in in the browser or OneDrive client, as warnings may be for a different account than the one being checked.
2. View detailed Microsoft storage usage
   • Go to the Microsoft storage page and sign in: use the Sign in link under “How to check how much storage you have used”.
   • After signing in, select the Microsoft storage section to see:
     • Total quota and used space
     • Breakdown of usage across OneDrive, Outlook.com attachments, and other services.
3. If the cloud storage is actually near full
   • Either reduce stored files (delete or move files out of OneDrive, remove large attachments, etc.), or
   • Renew or buy more storage if needed. If a Microsoft 365 subscription has expired, renew it to restore the higher quota.
4. If Outlook.com shows a mailbox warning
   • Mailbox storage (15 GB free, or up to 100 GB for Microsoft 365 subscribers) is separate from cloud storage, but exceeding cloud storage can still block sending/receiving email even if mailbox usage is low.
   • In Outlook.com, open Settings and search for Storage to see mailbox usage and clean up folders if required.

If the warning emails are going to an address that is a secondary alias or an old account, check that specific Microsoft account as well; storage overage on an old or secondary account can generate warnings even if the current primary account looks low.
