Our organization currently has reached 98% OneDrive usage. I would like to know if OneDrive will become read-only immediately after reaching 100%. Does this mean that all users will not be able to edit or upload new files, or will they only be affected after 30 days?

Any reply would be greatly appreciated.

    Dear @西湖IT管理员,

    Good day. Thank you for reaching out!

    Based on your description, please allow me to provide some information with you:

    The article you provided advises that action should be taken within 30 days from the date of notification. Failure to act within this timeframe will not immediately affect the data, but after 30 days, access will be restricted to read-only mode

    When your OneDrive for Education storage hits 100%, it does not become read-only immediately. This means that all users will not be able to upload or edit files at that point. However, you won’t experience any immediate data loss, and users will be able to access their existing files.

    Users can't upload or edit, they can still go through their files, delete some if needed, and free up space. It's important to actively manage storage before it hits that limit to avoid disruptions. If you'd like to avoid these storage ceiling issues, consider reviewing the storage allocation and usage between your users or possibly requesting additional storage from Microsoft Support if necessary.

    Your understanding and co-operation are highly appreciated. Thank you for your precious time. Have a nice day!

    Dear @西湖IT管理员,

    Good day. Thank you for your response!

    Yes! I would like to reaffirm and reiterate the point with you.

    • When your organization’s OneDrive storage reaches 100% capacity, users are not immediately affected in terms of data access. However, the system will enter a read-only mode, meaning users can no longer upload or edit files, though they can still view, download, and delete existing content. Microsoft typically provides a 30-day window from the date of notification for the organization to take corrective action such as cleaning up storage or requesting additional space.
    • If no action is taken within that timeframe, OneDrive functionality on the client side may be impacted, including issues with syncing and saving files locally. To avoid disruptions, we strongly recommend proactively monitoring and managing storage usage and, if necessary, contacting Microsoft Support to explore options for increasing your storage allocation.
