Reason Why Email Duplication in Our Outlook

I am working with company with multiple branch office in Malaysia. Sometimes we got report from users, that their email duplicate or receiveing same email a few times.

There are several reason why this issue occur and a few of it is:
             1) Outlook failed to update email server that email has been download. Normally it's due to network interuption. Cause, the email will be dowloaded for the secon times. We need to let users know, for every email, please let download complely. However, if it is not beyond our controll, we need to ignore or delete the unnesessary.
              2) Senders face error on thier end.
                  If we findout, same person delivered same email to us, but others are not, it's posiblity the senders outlook has a problem. Most probably because of the PST file cannot grow or insufficient storage.
