Hi ​@Raja K, welcome to the Box Community!

To better assist you with the storage and upload issue, could you please share the specific error message you're encountering or provide additional context?

Also since you mentioned you're using company-owned Box storage, may I confirm whether you're uploading files as a collaborator to a shared folder owned by another user in your organization? I ask because your account currently shows no storage usage, which suggests this might be the case.

If so, we recommend reaching out to the folder owner directly so they can review their storage allocation. For further reference, we also have a related community topic that may help:

Thank you, and I look forward to helping you resolve this!
