[How can we access NSF file without the ID file?]

Thank you all for your advice! The issue has been resolved.

[How can we access NSF file without the ID file?]

The legal department of our company has asked us to restore a particular users email from backup from 2 years ago.  We were able to find a couple of NSF files from the requested time period, but no ID files and we have since migrated from Notes to Exchange.  So is there a way to recover the email from NSF file without the ID file and without the Domino server?  We think the files were generated with Lotus Notes version 7.
