Department access control is a feature to restrict access to view department information and profiles of other users in different departments.

The following restrictions are applied:

• Restrictions on viewing information of users and departments
  The display name of the user who belongs to the inaccessible department is replaced by the alternative notation "User (not visible)". You cannot obtain information of users and departments for which you do not have permission, even via Kintone API.
• Restrictions on viewing user profiles
• Restrictions on search
• Restrictions on viewing items and options
  Using user selection fields and recipients of comments are also restricted.

Refer to the following page to check what kind of restriction will be applied.
