Why are some documents are sent to recycle bin while the user does nt have right to delete?
One explanation could be that the documents represent failed import tasks. The server allows users to back out of document creation, and the partially-formed documents go to the recycle bin. This is allowed even if the user wouldn't have rights to delete a completely-created document in the same location. The user might not even be aware that this happened - they probably just saw an error dialog, and didn't realize that a document was created and moved to the recycle bin.
That's just a guess... without more information it's hard to give a concrete answer. Have you asked those users about it?
Hi Mariam,
Who does it show as the user who deleted it? In the recycle bin in the client there is a 'deleted by' column which can be enabled. Workflow can delete documents to the recycle bin also.
Hope this helps point you in the right direction :)
Cheers!
