    Outlook to Notes - A Rare Conversion

    Migrating from Outlook to Lotus Notes is not the most common path when moving from one office email system to another – however you might have exhausted all other possibilities.

    Given the degree of work that is required in converting between these two formats – Microsoft Outlook uses .PST files to store emails while Lotus Notes uses .NSF – you should be absolutely certain that migration is warranted and required for your users. Checking our articles Microsoft Exchange vs Lotus Notes: A Comparison and Comparative Analysis of Microsoft Exchange and Lotus Notes might well help in forming a decision.

    The thinking behind this is simple – there may be scope to retain access to your soon-to-be-retired email system for legacy access purposes. Very few emails older than a month require regular, daily access.

    You might find that embarking on a mass email conversion could be a massive expense that simply cannot be justified. It might be simpler to simply roll out Lotus Notes, setup your new users, and send them on their way. There is also a chance that you could maintain limited access to Outlook or employ a PST reading tool.

    However if you want to migrate email from Microsoft Outlook to Lotus Notes, you’ll find that your options are restricted.

    Restricted Options

    Options to migrate email from Microsoft Outlook to Lotus Notes are limited The problem is that such a conversion usually takes place in the other direction.

    Many organizations over the past few years have migrated away from Lotus Notes and to Microsoft Outlook, particularly since the rise of Exchange as a push email solution.

    Very few businesses and other large bodies are migrating to Lotus Notes – if they were, there would be more choice on offer.

    The suggested method for converting your Microsoft Outlook .PST format email archive files into a format suitable for use with Lotus Notes is Transend Migrator, a premium solution that usefully comes with a trial version for assessing the suitability of the product.

    Advanced Options provide various program settings to be applied to your file conversion. These settings cover things like exporting headers or declaring a calendar as public.
