We have the most recent version of Retain, it's been running for nearly 2 years without issues. A few months ago we tried to migrate some user archives into the Retain system. We'd been doing this without problems for over a year. We get an error the the migration tool can't find the groupwise UUID. The error in the log looks like this

[WARNING] Error getting UUID from GroupWise.
[ERROR] Exception: Error getting UUID. Check user's visibility setting.

We're stumped and it seems that Gwava/Microfocus is too. Anyone have any similar issues?
