To efficiently remove duplicate contacts, tasks, and notes in Outlook, you can start by manually sorting each folder by fields like name, subject, or modified date, which helps identify and delete duplicates one by one. While this method works for small volumes, it can be tedious for larger Outlook data. A more efficient solution is using an automated tool like SysTools Outlook Duplicate Remover, which allows you to scan and remove duplicates from multiple mailbox items—including contacts, tasks, and notes—in one go. You can set matching criteria (such as full name, email address, or subject) to precisely detect duplicates, and choose whether to delete, move, or mark them.
