Personal Cloud Storage asking to add space when only at 1%

Question

I am the account subscription holder, I see that I do have the 1TB of storage available of which I'm using 5.6GB. I'm trying to add 78 GB and I get a message saying I need to add 40.7 GB to my personal space?

Answer 1

The message is referring to the unified Microsoft cloud storage quota, not just the free space inside the 1 TB OneDrive allocation.

Key points:

1. Microsoft personal storage is shared
   • OneDrive files and photos
   • Outlook.com pictures and attachments
   • Other files stored by Microsoft apps and services All of these count against the same Microsoft storage quota.
2. Why it asks to “add 40.7 GB” when OneDrive shows ~1% used
   • The 1 TB figure is the OneDrive file storage allocation that comes with Microsoft 365 Personal/Family/Premium.
   • The “need to add 40.7 GB” message comes from the overall Microsoft storage system when the account is over its unified quota.
   • This can happen if the account’s current plan/quota is smaller than the total data already stored across OneDrive + Outlook.com + other services, even if OneDrive itself shows plenty of room.
3. How to confirm what is actually full
   • Go to the account dashboard and open the Microsoft storage section to see:
     • Total storage quota
     • How much is used and by which services
   • This view is the authoritative source for whether the account is over quota.
4. How to resolve There are only two supported ways to get back under quota:
   • Delete content until the total used is below the quota:
     • Remove large files and photos from OneDrive (including items in the OneDrive Recycle Bin).
     • Clean up Outlook.com by deleting emails with large attachments and emptying Deleted Items.
   • Or buy/extend storage:
     • If using a free account, buy a Microsoft 365 subscription to increase both mailbox and cloud storage.
     • If already on Microsoft 365 Personal, Family, or Premium, additional file storage can be added on top of the included 1 TB; only the subscription holder can extend storage.

If the Microsoft storage page shows the account is over quota even after cleanup, wait for the quota to refresh (can take several hours). If it still looks wrong after that, contact support from the storage/help pages referenced in the documentation.
