Migration of large sized Lotus Notes .NSF file to MS Outlook is coupled with lots of issues and many error messages arise in such situations. In particular, when the point comes to migrate 4MB or above email file from Lotus Notes to Outlook. In this article we will be discussing issues and resolutions related to this problem.

Microsoft provides an exclusive service for migration known as ‘Microsoft Transporter Suite'. This utility is used to export user mailboxes from Lotus Domino Server to MS Exchange Server in an easy way. But sometimes during migration, you receive following error message:

The message was migrated without the attachments. This error might be due to configuration limitations on the server.

Error details: Maximum request length exceeded.

Reasons behind this issue

Foremost reason for the above mentioned error is the default limit in ASP.NET and that is 4 MB (maximum). Actually, Web services does not migrate attachments that are larger than default limit i.e.4MB until and unless some additional configuration is made.

Solution

In order to get rid of this ...
... problem, some changes in settings need to be performed. You will need to increase the input stream buffering threshold value. You may also need to increase the execution time-out period. To do this, follow these steps:

Start Notepad.

Under the following directory, open the Web.config file:
drive:\%PROGRAMFILES%\Microsoft\Exchange Server\ClientAccess\exchweb\ews

In the Web.config file, add the following line after the (system.web) tag:

(httpRuntime executionTimeout="1200" maxRequestLength="51200" /)

It is to be noted that the executionTimeout attribute is in seconds. This attribute indicates the maximum number of seconds that a request can run before ASP.NET automatically stops the request. The maxRequestLength attribute is in kilobytes (KB). Adjust each attribute as appropriate for your environment.

Save and then close the Web.config file.

Restart the World Wide Web publishing service.

By following these steps, you can be assured of increase in the input stream buffering threshold value. Now if you can migrate the email of 4MB size from Lotus Domino to Exchange Server, there would be absolutely no problem.

In most of the cases, Microsoft Transporter Suite proves to be suitable and worth when comes the need to migrate email items from lotus notes to outlook. But this is not the case all the time. This utility generally fails when other complexities arise during migration. Therefore, one should deploy third party professional email migration tools that are easy to use and free from any complexities. With Lotus Notes to Outlook email migration software, you can easily convert emails, attachments, images, drafts, sent items, journals, calendar, to-do list, appointments, tasks, address book, folder and sub-folders of .NSF file to .PST or Exchange Server and without any file size limitation.
