# Expiration Date SHOULD Be Set for Anyone Links

## Description

Files that are stored in SharePoint sites, Groups, and Teams for months and years could lead to unexpected modifications to files if shared with unauthenticated people. Configuring expiration times for Anyone links can help avoid unwanted changes. If Anyone links are enabled, the expiration date SHOULD be set to thirty days or as determined by mission needs or agency policy.

## Policy

* An expiration date SHOULD be set for Anyone links.
* Expiration date SHOULD be set to thirty days.

## Licensing Considerations

Any tenant with OneDrive for Business licensing can access this setting.
