How to fix NSF Issues:
-Copy the NSF file into a new local location that has Lotus Notes
-Using the Command prompt go to Lotus Notes home. (i.e. c:\lotus\notes)
-Run the commands:
(Enter the user's Notes password if prompted)
ncompact.exe -c <filename>.nsf
-Once the file has been fixed and compacted. Rename the original NSF in source (i.e. _bkup or _currupt) to distinguish the corrupt version from the fixed one.
-Add the fixed NSF to source and process as needed.
