I have no active plans of 365 or Onedrive on this account but I have a total storage of 121.5 GB including free 5 GB. This is not my main account but something I use for Copilot whenever I don't have access to my pc. I want to know where I can check if someone has shared storage with me or I got this due to some promo? I went to storage option in Onedrive but that only shows a few MB's used in email attachments.

Microsoft 365 and Office | OneDrive | Other | Windows

    I understand that your account shows 121.5 GB of storage despite having no active Microsoft 365 or OneDrive subscription, and you'd like to identify where the additional storage comes from. Could you please clarify a few details?

    Sign in to https://account.microsoft.com/storage and check whether the additional storage appears under your cloud.

    Where exactly do you see the 121.5 GB total? Is it in OneDrive or Outlook.com? Have you ever had a Microsoft 365 subscription?
