Batch uploading of emails through drag and drop from Outlook to the LW web interface has been a huge time-saver. However, if one or more of the emails has already been uploaded to LW, LW will bring up an error screen stating a duplicate email was found and asking if the user still wants to upload the duplicate email. There is currently no way of telling which is/are the offending email(s) without uploading each email one at a time (which defeats the purpose of batch uploading). It would be great if LW gave the option to continue uploading the non-duplicate emails.
