>> Resolution:
-----------------------------------------
Go to the Option tree on the left in horde, and click the Mail link under it. In the right pane, tick "When deleting messages, move them to your Trash folder instead of marking them as deleted?" and select a thrash folder in the "Trash folder:" option just below it. That would resolve the error.
