Question details

Users need to understand why recipients are being forced to sign into a Microsoft account to upload files to a shared folder, even when the link was intended to not require a login.

Why Does OneDrive Require Sign-In to Upload to a Shared Folder?

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Sharing a folder link with external or anonymous users so they can upload or edit files.
Observed behavior: Recipients are prompted to sign in before they can upload or edit files in the shared folder, preventing anonymous contributions.

Before you start

Ensure you have administrative or owner access to the OneDrive folder being shared, and verify that your Microsoft 365 organization policies allow anonymous file sharing.

Solution 1Recommended

Verify Sharing Link Permissions and Type

Ensure the link was generated with 'Anyone with the link' permissions and editing rights enabled to bypass sign-in requirements.

OneDrive uses sign-in requirements primarily to protect shared content and identify contributors. However, if anonymous uploads are permitted by your organization, you can configure the link settings to bypass the login prompt.

Open OneDrive Sharing Settings

Navigate to the folder you want to share in your OneDrive online interface, right-click it, and select 'Share'.

Modify Link Access

Click on the current link permission settings (usually defaults to 'People you specify can view').

Enable Anonymous Editing

Select 'Anyone with the link' and make sure to check the box for 'Allow editing', then click 'Apply'.

Copy and Distribute Link

Copy the newly generated link and send it to your contributors. They should now be able to upload files without signing in.

Verify Sharing Link Permissions and Type

Organization Restrictions: If 'Anyone with the link' is grayed out or unavailable, your organization's IT administrator has disabled anonymous sharing at the tenant level for security purposes.

Solution 2

Use the 'Request Files' Feature

If standard folder sharing enforces sign-in, use a dedicated file request link to allow secure, anonymous file collection.

Frequently Asked Questions

Can I completely bypass the OneDrive sign-in requirement for external users?

You can bypass the sign-in requirement by generating an 'Anyone with the link' sharing link with editing enabled. However, if your Microsoft 365 organization has disabled anonymous sharing, users will still be forced to sign in regardless of your link settings.

Why is the 'Anyone with the link' option grayed out in my OneDrive?

This option is grayed out when your organization's IT administrator has restricted anonymous sharing at the tenant level. This is a common security and privacy measure implemented by businesses to track exactly who is accessing and modifying files.

How can people upload files to my OneDrive without creating a Microsoft account?

If you are using OneDrive for Business, you can use the 'Request files' feature. This generates a specialized link that allows anyone to upload files to a specific folder anonymously, though they cannot view or edit the folder's existing contents.
