Sharepoint - Group of users cannot see items in the document library

  1. Manage Files With No Checked In Version: Go to Library Settings and click the "Manage files which have no checked in version" link. If users have uploaded files but not checked them in, the users who uploaded the documents will be the only ones who can see them. Fortunately, the site owner can take ownership of checked out files, then check them in.
  2. Version Access: Go to Library Settings and click the "Versioning Settings" link. If "Content Approval" is turned on, then only people with access to Approve items will be able to see unapproved items. Similarly, if "Create major and minor (draft) versions" is checked, double-check what the "Draft Item Security" is set to-- you probably want it to be "Any user who can read items"
  3. Permissions: Finally, go to Permissions for this document library and confirm that there are no documents or folders with unique permissions.
