Having duplicate items is always annoying for users. Whatever email client you’re using, be it Outlook or IBM Notes (formerly known as Lotus Notes), duplicate items can easily be included in your mailbox without you noticing. Duplicate items are always harmful to any type of mailbox, be it PST or NSF database. Here in this blog post, we’ll learn why duplicate items occur in the NSF database and how we can remove duplicate emails in Lotus Notes.

Duplicate Items in NSF Database

In an NSF database, a duplicate item can be an email message, contact or any other item. A duplicate item in the NSF database occupies exactly the same space what an original item does. Sometimes users take it easy, but they don’t know how much trouble it may cause them. The common duplicate items in IBM Notes are found in their emails and contact information. Do you know why duplicate item occurs in the NSF database? Have you ever tried to find it out? If you use IBM Notes client in a regular manner, it’s quite obvious that you receive hundreds/thousands of email messages daily. Some companies and organizations send email messages to millions of users on a daily basis for their promotion. It may happen that you receive an email message twice or multiple times which causes duplicity for sure.

Also, you may face duplicity in contact information. How?

Merging two or multiple NSF database files(names.nsf) of a single account can cause duplicity in your contact information.

Importing the address book of an ex-employee to another employee’s address book can create duplicate contacts.

Synchronizing names.nsf database file with the contacts which are already present in the address book can also cause duplicity in contact information.

Having duplicate items in an NSF database not only creates troublesome situations for users but also causes corruption. Duplicate items increase the file size of the NSF database. We all know that a large file is always prone to severe issues. It can affect the performance of the IBM Notes application. But the worst impact is corruption which may lead to a data loss situation.
