Migrating data from Lotus Notes to Outlook can be a complex process, but it can be done manually by following these general steps:

Note: Before you begin, make sure you have a backup of your Lotus Notes data and a plan in case something goes wrong during the migration.

Install and Set Up Outlook:
Ensure that Microsoft Outlook is installed and set up on the computer where you plan to perform the migration.

Export Data from Lotus Notes:
Open Lotus Notes.
Click on "File" > "Export."
Choose a location to save the exported data.
Select the data you want to export (e.g., emails, contacts, calendar).
Choose the export format (CSV, Excel, etc.) for each type of data.

Convert Notes Emails:
Lotus Notes emails are typically in .NSF format, which Outlook doesn't support. You may need a third-party tool to convert them to a compatible format like .PST.

Import Data into Outlook:
Open Outlook.
Click on "File" > "Open & Export" > "Import/Export."
Select "Import from another program or file" and click "Next."
Choose the file type you want to import. If you converted Lotus Notes emails to .PST, select "Outlook Data File (.pst)."
Browse to the location of your exported Lotus Notes data.
Select the data you want to import (e.g., emails, contacts, calendar).
Follow the on-screen prompts to complete the import process.

Verify and Clean Up:
Once the import is complete, review your data in Outlook to ensure everything transferred correctly.
You may need to organize your emails, contacts, and calendar entries in Outlook to match your previous Lotus Notes setup.

Configure Email Accounts:
If you were using Lotus Notes for email, configure your email accounts in Outlook to send and receive emails.

Testing:
Thoroughly test your Outlook setup to make sure everything is working as expected. Send test emails, check calendar entries, and verify contact information.

Training and Support:
Provide training and support to users who are transitioning from Lotus Notes to Outlook, as the interface and features may be different.
