Table of Content

    Summary: Over the last three decades, HCL Notes has seen many major and minor versions. Unfortunately, the NSF files are not backward compatible. This means when you open an NSF file in the lower version of Notes, it can throw an error. In this article, we discuss a few ways to open the NSF file in lower versions.

    HCL Notes, as we know it today, has a long history. Originally developed by the Lotus Development Corporation, IBM bought Lotus Notes in 1995.  HCL Technologies bought IBM Notes in 2018, and it is since then called HCL Notes. These multiple transitions have led to numerous updates, sometimes with little compatibility.

    These incompatibilities are most evident when you try to open a .nsf file that was created in a higher version of Lotus Notes in a lower version of the software. For example, if you created a *.nsf file in version 9, you may have problems when you open it in 8. X.X versions.

    Open a .nsf file in the lower versions error

    The easiest option is to upgrade your Notes. But if that’s not possible, read on as we show you two ways to fix this issue. 

    Manual Method – Open a .nsf file in the lower versions

    Here is a series of steps you can take to open the *.nsf file in a lower version. 

    Step 1: Backup your *.nsf file

    Before attempting to open a *.nsf file in a lower version of Lotus Notes, create a backup of the file. This will ensure that if anything goes wrong during the process, you will still have a copy of the original file.

    To create a backup of the *.nsf file, simply make a copy of the file and store it in a safe location. This can be done by copying the file to an external hard drive or USB drive, or by simply creating a copy of the file on your computer. 

    Step 2: Rename the *.nsf file

    The next step is to rename the *.nsf file. This is an important step because it will prevent you from accidentally overwriting the original file. To rename the *.nsf file, simply right-click on the file and select “Rename”. Then, give the file a new name, such as *.old or *backup or any other name for easy identification. 

    Step 3: Open the lower version of Lotus Notes

    Next, open the lower version of Lotus Notes that you want to use to open the *.nsf file. To do this, double-click on the Lotus Notes icon on your desktop or search for Lotus Notes in your Start menu. 

    Step 4: Open the old file

    Once Lotus Notes is open, go to File > Database > Open. In the “File name” field, select the *.old file that you renamed in Step 2. Then, click “Open” to open the file. 

    Step 5: Do not upgrade the file

    When you attempt to open the *.old file, Lotus Notes will recognize that the file was created in a higher version of the software. It will then prompt you with a message asking if you want to upgrade the file to the current version. To open the file in its original version, select “No” when prompted to upgrade the file.

    These steps may open the *.nsf file in a lower version, still, differences in encryption or problems in the *.nsf file itself may cause problems. More importantly, you can end up with a file corruption, causing you to lose your data. Plus, this manual method requires a fair amount of technical expertise and effort as well.

    Another option is to install Notes 7 as this version is deemed to be compatible with both Notes 8 and 9 versions. 

    Using Third-party Tools

    An easier option to open *.nsf files in a lower version or the different platforms such as Outlook by using third-party nsf to pst converter tools like the Stellar Converter for NSF. This is a powerful tool that converts inaccessible *.nsf files to PST format and makes it easy to migrate your data to Outlook.

    Final Thoughts

    Opening a *.nsf file in a lower version of Lotus Notes can be complex. The steps mentioned in the manual method can help you view the contents of the *.nsf file in lower versions of Lotus Notes, but they can also cause other errors including permanent data loss.

    A better option is to use third-party tools like Stellar Converter for NSF that are easy to use and come with an intuitive and friendly user interface.
