Now, easily migrate emails of file size 4 MB and more from NSF to PST mailbox

Wednesday Oct 31, 2012

With the changing needs and requirements of organizations and individuals, sometimes email migration also becomes the need of hour. Generally, users find the process of NSF to Outlook migration quite hard and tedious. But, upon finally taking the decision of migration of Lotus Notes (NSF) to Exchange Server (PST), the foremost matter of concern is issueless migration which is free from any kind of complexity or error.

Microsoft provides a wondrous tool ‘Microsoft Transporter Suite’ for Lotus notes to Exchange server migration. This tool makes the process of migration extremely simple and easy. But the migration results provided by this tool lack accuracy at times and it also create issues with large size of NSF file. A similar problem faced by users is when NSF file size is approximately 4 MB or above. The migration process simply freezes in such situations and generates the 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.”

Such errors crop up because the web services are capable of migrating attachments of size below 4 MB only. To increase the default size, configuration settings can be altered, i.e, input stream buffering threshold value and execution time-out period should be increased.

The following steps need to be followed for making the required changes:

  1. Open Notepad
  2. Under the directory “drive:\%PROGRAMFILES%\Microsoft\Exchange Server\ClientAccess\exchweb\ews “ open web.config file.
  3. In web.config file, after tag, add

Here, executionTimeout attribute indicates the number of seconds uptil which the request can keep running and maxRequestLength attribute is measured in Kilobytes(KB).

  • Save and exit web.config

Now, again try to migrate the emails having size of 4 MB or above. Since the above steps increase the input stream buffering threshold value, therefore the problem generally gets resolved. But, in case the problem still persists need not panic as there are efficient third-party software tools available for migration of NSF to PST.

NSF to PST converter is one such expeditious utility which accurately converts the NSF mailbox items such as emails, attachments, journals, tasks, notes, images, appointments, etc into PST file. It facilitates the users to migrate multiple NSF files in to PST files simultaneously. Moreover, the converted files can also be saved in Text or RTF format. This efficacious utility ensures that the original structure, properties and data of the NSF file remains completely unaltered on converting it into PST file.
