External Users in Wrike
External users have similar rights to regular users but can’t share tasks, folders, or projects, and they aren't included in the My Team group. External users can only see the contact information of people who share common tasks, folders, and projects with them.
Account owners and admins on Enterprise Pinnacle accounts can adjust rights for external users in the account. Learn more about it here.
External users are able to:
See, comment on, and attach files to tasks, folders, and projects shared with them.
Change the status of a task.
Export reports shared with them (Reports are only available on Business and higher accounts).
A detailed chart comparing the rights of license types, and what each can and can't do, is available on our User Rights by License Type help page.
