As a location manager, you can unarchive or restore users that were previously in your location.
To a user that has been archived in ExpandShare, start by going to the location tab.
Click the search icon at the top right of the screen, click this drop down and select archived.
Search for the user by name, and their profile will show up. Click on their name to be brought to their profile.
Clicking the three dots at the top right of the screen presents multiple options, and selecting an archive user will make this account accessible again.
