As cloud technology becomes advantageous, more and more organizations are switching to it from an on-premises environment. Organizations using HCL Notes (formerly known as IBM Notes or Lotus Notes) are not an exception. Due to this, there is a huge demand for email migration from Lotus Notes to Office 365.

However, migration from lotus notes to Office 365 isn’t easy to perform, as Lotus Notes stores its data in a .nsf file. And, Microsoft application support only .pst file format. So, it becomes impossible to manually migrate data between these two environments. But, there are some easy workarounds to perform the migration.

Techniques to Perform Email Migration From Lotus Notes to Office 365

Apart from file conversion and import tool combo, there are two easier workarounds to perform the migration:

  1. Using IMAP connector to migrate emails from Lotus Notes to Office 365
  2. Using Automated Tool to Directly Import NSF File Data Into Office 365 Account

Technique #1: Manually Migrate Emails Using IMAP Connector

Follow the below step-by-step process for email migration from Lotus Notes to office 365 manually:

Step 1: Save NSF Files

As we have explained earlier that Lotus Notes support .nsf file, therefore, you need to take backup of your NSF file of Lotus Notes. This will help you to recover the mailboxes if manual migration fails.

Step 2: Generate new user mailboxes for each NSF file

In this step, you need to create a destination user account in Microsoft Office 365 for each NSF file. Create a user name with the same name as the NSF file, this will help you easily map the NSF file and Office 365 user account.

Step 3: Enabling IMAP TCP/IP Port

This is a repetitive process that needs to be done for each user account. Follow the steps below to enable IMAP TCP/IP ports:

  • Go to Admin Center of Domino in Lotus Notes
  • From the configuration tab, open server document that performs IMAP services
  • Click on the Ports, then select Internet Ports, and then click on the Mail tab.
  • From the IMAP column, change the value status of TCP/IP port to Enabled.
  • Hit the Save button to implement the changes and then close Lotus Notes

Step 4: Synchronization with IMAP Connector

The final step for email migration from Lotus Notes to Office 365 is to use IMAP Connector to synchronize both environments.

Drawbacks of Manually Migration to Office 365 from Lotus Notes

  • Generally firewall and proxy server of Lotus Notes connection blocks internet connection.
  • Cannot migrate NSF file of size greater than 1GB
  • This manual approach doesn’t support Calendar migration so that needs to be done separately.
  • Complex and time taking process.
  • Only migrates 15 user mailboxes in one go.
