DXL-MSG facilitates the conversion of emails, contacts and other items from HCL/IBM/Lotus Notes/Domino to Microsoft Outlook both for migration purposes and for use with E-Discovery and forensic tools that work with MSGs and/or EMLs.

DXL-MSG converts emails, contacts, appointments, phone messages, tasks and other items stored on DXL files to MSG files and, optionally, EML files. It can convert millions of DXLs in a single run. The product is provided in two forms: One is a Windows console program that can be run from the command line, or called from batch and cmd files, from scripts and using remote launchers such as PSExec. The other form is a set of APIs: The managed API can be invoked from C# or any managed language. The unmanaged API can be called from native C++ or LotusScript.

DXL-MSG is intended for use by system administrators, migration experts, forensic engineers and E-Discovery workers.

DXL-MSG must be run on a Windows system with both Microsoft Outlook and either the Notes client or Domino server installed. Specifically:

  • Outlook 2010, 2013, 2016 or 2019 (32- or 64-bit).
  • A 32-bit Notes client version 6.5 or later or Domino server.

Try it!

Please try our demo/evaluation package. This version of the product is fully functional except that it converts random digits in message text to hash characters (#). Alternatively send us a sample of up to a dozen DXLs and we will convert them for you and send you back the MSGs (and EMLs if requested). You may also learn more about DXL-MSG by reading the DXL-MSG User Guide online.
