Was out of town for about 10 days, when I returned and started deleting, moving, or opening junk email, I could not do so for those dated Aug 31-Sept 4.  All those since that time can be handled as in the past, either deleted, moved, or opened.

The error message says "Unknown Error", so that told me nothing.  Suggestions???
