I granted Contribute permission to users. I modified the contribute permission and checked override checkout and approve items. even after this modification users aren't able to copy or move documents from one library to target library. "Inadequate permissions to "target library" to complete this operation. Please suggest. Per Microsoft Contribute permissions is sufficient for this action. https://support.office.com/en-za/article/Work-with-site-content-and-structure-30fcaad9-02b1-4347-8b03-e1ccc5a4c19f
While the Contribute permission level is sufficient to access the "Manage Content and Structure" page, the specific permissions required for copying or moving documents between libraries are Manage Permissions, Manage Web Site, and Add and Customize Pages.
