Effortless Steps to Migrate IBM Lotus Notes to Office 365

I recently tried to migrate from Lotus Notes to Office 365 manually, and there I encountered some challenges. As a user, I think you can also face this problem. Hence, I am sharing this article so you can easily upload the Notes NSF file database to Office 365.

Microsoft Office 365 is the most popular in the cloud environment. It offers many advantages over the email platform that HCL Notes, formerly known as IBM Lotus Notes, did not provide. Every business wants to migrate to Office 365 from other platforms, especially those using IBM Lotus Notes.

How to Import from Lotus Notes to Exchange Online

There are two different tricks by using that users can migrate the Domino Notes database into Office 365. As per your choice you can try one of them.

Method 1: Manually Migrate from Lotus Notes to Office 365 via IMAP

When you wish to migrate all of your data from IBM Notes to Microsoft Office 365 manually, you may use it. Follow the four steps below:

Step 1: Take Backup in NSF File

Before performing the migration, creating a backup in an NSF file is important to avoid data loss that mistakes might cause during the transfer process. For backup, you can create Lotus Notes archives.

Step 2: New mailboxes

The next step is establishing new mailboxes for each user with a profile in the desktop email client for Lotus Notes.

Step 3: Enable IMAP TCP/IP Port

Open Domino Administrator in IBM Lotus Notes and take the steps listed below to enable IMAP for all users:

  • Select the Configuration tab.
  • Open the Server document for the server that is running the IMAP service.
  • Select the Mail Tab under Port>Internet Port.
  • Enable the default IMAP TCP/IP port. You must set the “TCP/IP Port Value Status” in the Mail column to “Enabled.” Select “Save.”

Step 4: Connect using IMAP Connector

To sync emails from Lotus Notes to Office 365, use the IMAP Connector.

Once you’ve finished the four steps, you can migrate from a Lotus Notes environment to an Office 365 environment. The IMAP connection has limits, but this method does not exceed them.

Limitations of migration using IMAP

Lotus Notes to Office 365 migration via IMAP has the following limitations:

  • If a firewall and proxy protect the Lotus Notes client, it will be unable to access the Internet.
  • If the Lotus Notes email client is disabled, IMAP connections will not be permitted.
  • The IMAP connection restricts the transmission of calendar entries, forcing manual entry generation, which slows down the transfer process.
  • Online data will be transferred to Office 365.
  • IMAP connection has a 1 GB email transfer limit.

Method 2: Using Lotus Notes to Office 365 Migration Tool

The previously described method has disadvantages and can’t be used by a user without technical understanding. The above technique is challenging to use if you need to transfer several accounts or mailboxes from IBM Lotus Notes to Office 365.


  • You can migrate one or more mailboxes from IBM Lotus Notes to Office 365.
