The Options page lets you specify whether or not OfficeTalk should perform duplicate checks every time a company or contact is added to the workgroup database.
You can specify that duplicate checks are performed by checking the Check for duplicates when adding companies and contacts check box. By default, duplicate checking will only be performed against contact records to which the user entering the data has at least read access. If you wish to extend duplicate checking to include records to which the user entering the data has no access then check the Also check against records to which the user has no access check box.
