I received an email from Microsoft stating that my storage is over 80% full, but I'm puzzled by it. I didn't find the email suspicious—the sender's email looked legitimate, and all links went to domains ending in .microsoft.com. However, my account has hardly anything stored; there's no OneDrive, no Outlook, and no Microsoft 365. I checked the Microsoft account's Storage section, and it says 0% used, with a tiny fraction allocated to OneDrive and no attachments on Outlook. I've only used this account for Minecraft Java and I haven't logged in on any Windows devices or linked it to a phone number. Given all this, I'm wondering why Microsoft issued this warning, especially since it seems like I'm using no storage at all. It feels like a mistake might have happened on their end, treating empty space as something significant.

You might want to double-check the sender's email address carefully; sometimes phishing attempts look very legit at first glance. But if you're confident in your email's source, it sounds like this is more of a Microsoft oversight.
You're not alone—I've seen several posts about this today! It seems like Microsoft might have accidentally sent that email to a bunch of accounts with no actual storage issues. It's likely just a glitch more than anything concerning your account.
Thanks, that explanation makes the most sense given my situation.
I encountered something similar! I used a free Microsoft account just for their services, and it filled up with promotional emails. If yours is just a custom email, that could explain why it seems empty. A lot of folks seem to be getting these mistaken warnings lately.
I don't have a free Microsoft email linked, but I finally get why others are receiving these too—I might mark this post as resolved!
If your email isn’t connected to anything like Xbox or other Microsoft accounts, it could very well be a fake email. I got a similar notice on my Gmail, but it was all linked to other services like Xbox Live. If you don’t have anything linked, I’d ignore it.
Just a heads up, you might want to treat any unexpected email from Microsoft cautiously, but given your description, it doesn't seem like a phishing attempt. They usually wouldn't monitor your hard drive, just the cloud services, so it’s probably a mistake on their part.

I checked the source code, and it looks fine—nothing suspicious there.
