Error during migration: Remove unresolved workitem from cache (4375988)

When using MNE to migrate Notes mailboxes, the following error message may appear:

"Problem encountered with worker program 10:10:09 Unresolved workitem found for (00000000-0000-0000-0000-000000000000)(server\mailbox.nsf) 10:10:10 DEBUG: Remove unresolved workitem from cache for user user1@emailcom:"

This indicates that MNE has encountered a corrupted item in the NSF file that it cannot process.

• Log Analysis (Optional): Examine the MNE log files to pinpoint the specific item(s) that triggered the error message. This step can be time-consuming and may not always yield a definitive result.
• IBM Tools (Optional): Run the IBM Fixup, Updall, and Compact tools on the NSF file. This may repair some types of corruption but might not resolve the issue if the corruption is severe.
• Create a New NSF Copy (Recommended): The most efficient solution is to create a new copy of the NSF file. This process inherently excludes corrupted items that Lotus Notes cannot parse, resulting in a cleaner, more migratable mailbox.
  • Open the original NSF in Lotus Notes.
  • Choose File > Application > New Copy.
  • Provide a name and location for the new copy.
• Migrate the NSF Copy: Use MNE to migrate the newly created NSF copy instead of the original. This should proceed without encountering the "Unresolved Workitem" error.
  • You can replace the original NSF with the new copy or export and modify the TSV file to import into MNE.
