Facing NSF File Error! Get Lotus Notes Converter to Open NSF File

The growing reliability on emailing utilities for inter-organization communication forces enterprise to go forth for quick, reliable and secure cost effective email clients. For instance, all users who are making use of Lotus Notes as their email application, usually face high maintenance charges, installation costs, functionality issues, increased help desk etc. All these drawbacks pressurize users to choose easy to use and simple email client like MS Outlook therefore, the need arise to migrate from Lotus Notes NSF to PST Outlook.



A user receives an error while migrating database from Lotus Notes with the Notes Migrator admin bulk migration process:

"ERROR: [4618-33-102-00004103] Unable to open NSF file 'cn=SERVERNAME/o=XXX/c=YY!!mail/SERVERNAME/username.nsf'"
where SERVERNAME = the mail server name containing the user's mailbox.


Problem Solution Specified

If it’s a local file, and there are no copies or replicas (either on a Domino Server or locally), then try to fix DB running either compact on it or fixup.

Note: Make a copy of affected DB before proceeding further.

Clients execs for both the process (also there are versions of server), located in Lotus Notes directory. Install Lotus Notes and call ncompact and nfixup properly.

Run nfixup -? or ncompact -? to see syntax

Notice: If no database is specified, it will run on all databases!

IBM recommends to first run fixup and if it fails, then try to compact –c to save anything which is still understandable (this runs a copy type compact). Extra options can also be used (eg. -i to ignore errors or -D to discard view indexes). Also, you have to run updall to update or to rebuild view indexes after recovery.


The Smart Process

First verify if the NSF file is available in the specified path. The TSV file row for the particular user can be modified to enter the correct path to the mail file and then attempt the migration again.

In many cases, the mail server name is incorrect and editing the value to reflect the correct mail server which includes NSF file should resolve the issue.

Moreover, a third party shareware technique is also available which will not discard the error, but could allow to import NSF files into multiple formats. And it is recommended that users first try the demo version of the application, if they get satisfied with the complete process then they can opt the license key.
