The latest version of Migrator for Notes to Exchange is 4.16.1

We are excited to announce a new version of Migrator for Notes to Exchange 4.16.1 is now available for download.

Migrator for Notes to Exchange (MNE) is a set of coordinated software applications designed to facilitate a variety of migration strategies for organizations moving from a Lotus Domino server, with Lotus Notes clients, to a Microsoft Exchange environment with Outlook clients. MNE can migrate either to a proprietary Exchange environment, or to a hosted Exchange service like Microsoft’s Office 365.

Look what's new:

Migration of oversized attachments to OneDrive

When you are migrating messages to an Office 365 target, you can now migrate oversized attachments to the Microsoft OneDrive store associated with the user mailbox. Oversized attachments are defined using the maximum size limit for attachments that is set in the Data Migration Wizard (or in the SSDM) on the Select Date and Size Filters screen.

You must register the Migrator for Notes to Exchange application with the Microsoft Azure portal and grant necessary permissions to allow the attachments to be migrated to OneDrive. For more information, see the Microsoft Azure AD Application Registration section in chapter 1 of the MNE Administration Guide and the [Exchange] MigrateOversizedAttachments parameter in the MNE Program Parameters Reference Guide.

A new Powershell cmdlet called Initialize-MNEOneDriveUserCollection is introduced to the Quest.MNE.PowerShell module to provision a user's OneDrive store before migration of user data to an Office 365 target. The cmdlet is useful when you enable the feature for migration of oversized attachments to OneDrive.

By default, the first time that users browse to OneDrive, their OneDrive store is automatically provisioned. In most cases, it is impossible to require that all users in a user collection log in and browse to OneDrive so that their OneDrive store is provisioned and ready. The new cmdlet is used to provision the OneDrive store associated with each user in a user collection so that all the required OneDrive stores are provisioned in advance of the migration.

Converting Notes RTF to HTML format

MNE uses a Notes RTF (rich text format) exporter to export Notes RTF to Microsoft RTF when migrating an RTF message body. MNE now supports converting the Notes RTF format to HTML. By default, this feature is disabled. You can enable the feature using the following new parameter: [Exchange] MigrateRtfToHtml. (194667, 111669)

Previously, MNE might encounter performance issues when using the Notes RTF exporter to export Notes RTF to Microsoft RTF. Also, MNE would extract embedded images and convert the images to DIB (device independent bitmap) format since OWA does not support RTF. The DIB format could cause the image file size to become very large. If you have encountered these issues, you might want to enable this feature to convert RTF to HTML.

The new feature has the following limitations:

  • If MNE is running in offline mode ([Notes] Offline=1) or the Notes User ID path or password is not set, the new feature is not enabled. MNE will revert to exporting Notes RTF format to Microsoft RTF when migrating an RTF message body even if the [Exchange] MigrateRtfToHtml=1 parameter is set.
  • The new feature only supports Memo type for the Notes client. For details see the following support article. If MNE fails to convert Notes RTF to HTML,MNE will attempt to export Notes RTF to Microsoft RTF.
  • Some application, document, database, view, or folder links might be lost after converting RTF to HTML.
  • The new feature supports Domino/Notes version 8.5.3 or later.


  • MNE now supports migrating from Domino server 11 using the Notes client 11.
  • MNE can now send migration summary email notifications to the migration administrator.
