Hi ​@sharrisonbellfirmlaw, 

Welcome to Box Community, and we’re glad to help with your error. 

Are you uploading files on a shared folder? It seems that the owner has reached his/her storage allocation. That’s why it’s returning the Account Storage limit reached error. 

Note that the folder’s ability to store contents will vary according to its owner’s free storage. At this rate, you should contact the owner to either free up his/her space or increase his/her account storage. 

Thanks for posting, and if you have questions, please feel free to reply this thread. 

We can no longer upload documents into Box.  Error message is “Account storage limit reached.”  How can I get more info on the storage limit?
