Please describe the problem:
Message pops up "Error While Storing Folder In-Box", then another window: "Summary and folder mismatch, even after a sync".  Message continues to pop up each time mail is retieved.  Seeing duplicate messages in intray.  When those are sent to trash, trash cannot be emptied.  After several re-launchings, trash can be cleaned out and pop's stop coming but can start again on a different day.  Also have seen all messages that were read and deleted but still in trash come back into intray as unread.

Steps to reproduce:
1. Wait for new mail to arrive.
2. Will see duplicate messages in intray.
3. Deleting messages to trash will cause trash to be locked, can't delete mail until several re-lauches later.


Actual results:
1.  Pop-up warnings continue. Trash can't be emptied.

Expected results:
Software corrects discrepancy and cleans up email storage.

Does this happen every time?
Yes.
