How can I check my OneDrive storage usage?

Instructions

There are two methods of viewing your OneDrive usage. 

• The M365 Account Sidebar will display USED storage - the amount of storage you are currently using out of your total quota.
• M365 Storage Metrics will display UNUSED storage - how much of your storage quota you have still available.

The numbers displayed in both your M365 Account Sidebar and your M365 Storage Metrics, when added together, should equal your total current quota. In the example image below, the M365 Account sidebar displayed 297.8 GB of used storage from a quota of 511 GB, and the M365 Storage Metrics for the same account displayed 213.15 GB of free space from a quota of 511 GB. Added together, these values equal 510.95 GB (511 GB after rounding).

M365 Account Sidebar

The storage usage displayed at the bottom of your M365 sidebar is the storage you are actually using which counts against your quota.

1. Log in to your M365 account
2. Scroll to the bottom of the left sidebar to view your storage usage.
   
   
    

M365 Storage Metrics

The M365 storage metrics page provides a detailed view of what folders and files are taking up the most storage in your OneDrive. The total storage used may not be the same as reported by the M365 account sidebar due to the way the storage is calculated. For the most accurate report of the OneDrive storage you are using, always refer to the M365 account sidebar.

1. Log in to your M365 account.
2. Click the gear icon on the top right of your screen. 
   
   
    
3. Click on OneDrive Settings.
   
   
    
4. Click on More Settings.
   
   
    
5. Click on Storage Metrics.
   
   
    
6. Review your OneDrive storage use.
   
   
    

Viewing the "Version History" of a Document

The Storage Metrics site also allows you to drill down into the site structure and see what is in the folders. Here you can also find the “Version history” of a document. 

1. Select Documents. 
   
    
2. When you see your desired document, select Version History.
   
    
3. You can use this page to view, restore, and delete older versions of a document.  The versions are seen as the most recent at the top. ​​​​​​
