Solutions For How to Migrate Lotus Notes to Office 365

Here, we include the best two approaches for performing this migration. One is a complex and time-consuming manual approach and the other is an automated professional approach to simplify the migration process.

Method 1. Use MONTI to Migrate Lotus Notes to Office 365

Microsoft Online Notes Inspector (MONTI) was developed by Microsoft. This tool is specially designed for the customers to gather the required data to perform migration manually.

Step 1. Download and double-click on the MONTI.exe.
Step 2. Then a wizard opens to Browse its location.
Step 3. Click on Browse to finalize the destination location and hit the Unzip button.
Step 4. Now all the documents are installed in the defined location.
Step 5. Go to the installed location and then open its guide and start performing its steps.


  • Administrators should have complete server knowledge, any of the mistakes can affect the data.
  • There are 86 pages in the MONTI migration guide, which is difficult to read and implement.
  • To work the long manual and execute each step is difficult.
  • There is no guarantee that data will be migrated successfully without any error.
