Duplicate e-mails can occur when e-mails from more than one computer being synchronized are requested from the e-mail server. This is the case if the function “Leave copy of messages on the server” was activated in a POP3 E-mail account.

In this case deactivate the Outlook function “Leave copy of messages on the server” so as not to save e-mails in your mail server and download them repeatedly.

To deactivate this function follow these steps:

Outlook 2007

  1. Open Outlook
  2. In the menu “Tools” click on “Account Settings“
  3. Highlight the POP3 E-mail account in question and click on “Change“
  4. Click on “More Settings“
  5. In the tab “Advanced” deactivate the check box “Leave copy of messages on the server“
  6. Confirm the changes by clicking “OK“
  7. Click on “Next“ and then on “Finish“

Outlook 2010, Outlook 2013 or Outlook 2016

  1. Open Outlook
  2. Open the Backstage area by clicking on “File“
  3. In the category “Information” click on “Account Settings” and “Add or Remove Accounts…”
  4. Highlight the POP3 E-mail account in question and click on “Change“
  5. Click on “More Settings“
  6. In the tab “Advanced” deactivate the check box “Leave copy of messages on the server“
  7. Confirm the changes by clicking “OK“
  8. Click on “Next“ and then on “Finish“

Please note:  If you use an IMAP account, this could also lead to duplicate e-mails. We do not recommend synchronizing IMAP accounts.

This message can be triggered by flawed Add-Ins from Third Party manufacturers. Outlook Add-Ins from Third Party manufacturers can hinder communication between SimpleSYN and Outlook.

Known problems: You may receive this message if you have the Apple Mobile Device Support Add-In installed, which is automatically installed by iTunes. The Add-in may make the PST file unusable for other applications when Outlook is shut down. Then SimpleSYN will also no longer be able to access the PST file.

To avoid the problem do not close Outlook while SimpleSYN is running.

If you are not using iTunes to synchronize an iPhone/iPod with Outlook, you could also deactivate the Add-in in Outlook.
