How to Access Lotus Notes Mail in MS Outlook?

IBM Lotus Notes used to be a popular email application, especially among businesses and large corporations. The deep integration of the email client and its other functionalities, such as calendar, instant messaging, file sharing, and much more made it so popular back in the day. But the same cannot be said now. These days Microsoft Outlook is the most widely used and preferred email client when it comes to corporates and SMEs.

Today, we will show you how to access your Lotus Notes mail in your Outlook for Office 365, Outlook 2019, Outlook 2016, or even Outlook 2013. We will also show you two different methods for the same – manual & automatic method(NSF to PST converter tool) . You can choose whichever is most appropriate for your organization.

Configuring Lotus Notes Access in Microsoft Outlook

There are two methods of accessing your Lotus Notes data in Microsoft Outlook. You can either go with the manual or the automated method, which is a lot simpler and takes way less time. Let’s quickly walk through the manual process once before taking a look at the automated process.

Manual Transfer of Mail Data from Lotus Notes to Outlook

Lotus Notes saves all its data in NSF file format. So, you need to manually convert the NSF file into a CSV file before importing it to Outlook. Let’s take a look at the steps.

Start the Lotus Notes program.

Tick all the emails you want to transfer. This step is necessary as you won’t be able to do that later. However, with the automatic process, you may be able to do it later as well. Let’s continue.

Now, look for the File menu and click it. Choose Export from the drop-down menu.

You will have to write a name down for the file and then select “Save As Type” as CSV. This is necessary, or else the exported file will be unreadable by Outlook.

Click Export again, and then you can continue with the import process.

Once you click on the Export button, a new dialog box will appear. It will be named Structured Text Support.

From there, make your own selection on the checklist and click OK. What you choose here will be based on your needs and requirements.

Now, let’s begin importing the CSV file that you just exported into the Outlook application.

Open the Outlook program that you have on your computer. Any version of Outlook will work. Whether that’s Office 265 Outlook, Outlook 2019, or 2016.

Now, look for the File menu button at the top. Click File and then choose Open, followed by Import/Export.

Now, a new wizard will pop up for you to import the CSV file.

Select “Import from another program or file” and choose the file type as CSV. Then click Next.

Choose the file and click Next.

Now, the import process will begin. This process can take either a sec or a couple of minutes depending on how much data you have in the CSV file.

All your Lotus Notes emails should be accessible in the Outlook program.

Limitations of Manual Transfer

There are a couple of limitations when it comes to the manual process, which is not the case with the automated process. Let’s take a look.

1. There is always the possibility of data loss. This has happened in the past, and it’s for this reason many corporations prefer the automated process.
2. The manual method doesn’t allow the transfer of specific email items, attachments, etc. For that, you will have to convert to PST format, which the automated tool Stellar Converter for NSF provides.
3. The steps are long, complex, and can take a while, which many organizations cannot afford.
4. You also cannot perform batch conversions.

Automated Transfer of Mail Data From Lotus Notes To Outlook

You will need a powerful tool, such as Stellar Converter for NSF, for the automatic process. It contains a ton of options, such as manual selection of the emails you want to move, data correction, and many more. Let’s examine this process’s steps.

• Download the Stellar Converter for NSF from Stellar’s official site and launch the program.
• Now, click on the ‘Browse’ menu. Then you will have to select the NSF file that you can save from Lotus Notes. Now, click the Convert button.
• You can also use the ‘Find’ option if you cannot find the file easily. This will allow the application to automatically locate files.

• After that, the converted mail data will appear in an organized view.

• Continuing with the process, click ‘Save Converted File’ and select the format as PST.

• Select the location to save the converted PST file, and then everything will be saved at that location.

Follow 5 Easy Steps to Import PST File into Outlook

Now, open the Outlook application and import the newly converted data into it.

Then navigate to File > Open > Import. This will launch a brand-new wizard, and from there, you will have to select “Import from another program or file.”

Then, click Next and choose the file type PST, which stands for Outlook Data File.

After that, click Next and choose the mail folders that you would like to import. Then click Finish.

Now, re-launch Outlook, and all your Lotus Notes data will be accessible from there.
