Understand OneDrive Blank Expiration Date Policies

A blank expiration date means no user-defined limit is set, but organization-wide Microsoft 365 policies may still enforce a time limit.

When you generate a sharing link in OneDrive and leave the expiration date blank, it generally means that you, as the user, have not set a specific time for the link to expire. For personal OneDrive accounts, this usually means the link will remain active indefinitely unless manually revoked.

However, if you are using a Microsoft 365 business or enterprise account, this does not guarantee the link will last forever. Your IT administrator can enforce an organization-wide sharing-link expiration policy. If such a policy is active, your link will automatically expire based on the administrator's default time limit (e.g., 30 days), regardless of whether you left the date blank during creation.

Check sharing settings

Log into your Microsoft 365 account, navigate to OneDrive, select a file, and click 'Share'.

Review link expiration options

Click on the gear icon or 'Link settings' to view the sharing options. Look for any mandated expiration dates that might be pre-filled or grayed out by your organization.

Personal vs. Business Accounts: If you are using a personal OneDrive account, links without an expiration date will typically never expire unless you manually delete them.

Frequently Asked Questions

How do I manually set an expiration date for a OneDrive sharing link?

Select the file in OneDrive, click 'Share', and open the Link settings by clicking the gear icon. Under 'More settings', look for the 'Expiration date' option and select your desired date from the calendar. Note that this feature may require a premium Microsoft 365 account.

Can an IT administrator change the expiration date of an existing link?

Yes. If a Microsoft 365 administrator implements or modifies the organization's sharing link expiration policy, it can apply to existing links. If those links exceed the new time limit, they will expire automatically.

What happens when a sharing link expires?

Once a link expires, it becomes permanently inactive. Anyone who clicks the expired link will receive an error message and will not be able to access the file. You must generate a new sharing link to restore their access.
