How to Convert Lotus Notes Archive to PST?

IBM Lotus Notes is a powerful workflow software that organizations use for information management. It organizes and stores mailbox information, such as emails, attachments, contacts, events, etc., in NSF files. With time, these NSF databases become bigger and make Lotus Notes and the computer system sluggish. To improve the performance of Lotus Notes, you can archive the NSF database.

What’s Archiving in Lotus Notes?

Lotus Notes archives and folders are Lotus Notes database files (.NSF files) containing archived mailbox items. Archiving is the process of copying old Lotus Notes data to another location. Users can archive their emails and other mailbox items to save space in their Lotus Notes account. Archiving is also a way to create a backup of your mailbox data.

Where are the Lotus Notes Archive Files Saved?

Usually, the archive files are located in the archive folder inside Lotus Notes data folder.  Thus, the default path is:

Lotus\Notes\Data\Archive\ArchiveName.nsf

To locate these files, follow these steps:

• Open Lotus Notes inbox and then open the Actions tab. Click Archive and select Settings. You will see a list of all archive files saved on your system.

• Select the archive you want to locate, and then click the Edit button.

The archive location will be displayed inside What Should Happen to the Selected Documents? section.
