I recently used an NSF to PST Converter to export my data from Lotus Notes to Outlook,ie.
Weeom Lotus Notes to Outlook Converter. It can save selected single or multiple items from the item view panel to file formats like MSG and EML. This Software takes care of all email data, including attachments, contacts, and calendar events, and preserves them accurately. This tool has no restrictions on processing large-sized Lotus Notes in Outlook PST file format. Users can use its preview options before conversion to confirm they have chosen the correct items to convert into PST format. Users can use its filter options to include or exclude items from the Lotus Notes NSF file. This conversion process is swift and safe for the users. The tool will maintain the folder hierarchy and data integrity. This Software is excellent for
Converting NSF to PST files. This tool is also accessible to new users, as it provides a simple user interface. Users who want to know the Software's functionality can use its free trial version and process the first 50 items per folder. This Software is easily compatible with all Outlook versions and Windows versions.
