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

The tricky here is that SimpleSYN cannot force Outlook to stop downloading an email a second time on another computer. If the first computer downloads the mail from the email server and it gets synchronized before the second computer downloads it, Outlook cannot detect that the email is already there. The second computer will than download the email from the email server and you got a duplicate. As the first email is also already synchronized, SimpleSYN assumes that the second download is intentional and synchronizes this copy too.

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:

  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“

If you are using a current version of Outlook:

  1. Open Outlook
  2. Open the Backstage area by clicking "File"
  3. In the "Information" category, click "Account Settings" and then "Add or Remove Accounts..."
  4. Select the affected POP3 email account and click "Change"
  5. In the next dialog, uncheck the "Leave a copy of all messages on the server" checkbox
  6. Confirm the changes by clicking "Next"

If SimpleSYN cannot establish a connection, please note the following:

  • Make sure SimpleSYN is installed and running on both the client and server computers.
  • One computer must be configured as the SimpleSYN server, and the other PCs as SimpleSYN clients.
  • All computers must be using the same major version of SimpleSYN (e.g., version 6.0). Different major versions (e.g., 5.0 and 6.0) are incompatible. You can find the version number in the main window under "Information."
  • All computers must be connected to the Internet.
  • Check that the Windows time, time zone, and date are set the same on both computers.

If these requirements are met, check the "Status" message on the client.

If the client displays "not connected":

  • Open SimpleSYN on the server and go to "Options" to display the server ID.
  • Open SimpleSYN on the client and go to "Options > Connect to a different server."
  • Enter the server ID there.
  • Save the settings.

If the client displays "Authentication failed":

  • Open SimpleSYN on the server.
  • Go to "Synchronization Settings > Manage Users."
  • Select "All Users", assign a new password, and save the page.
  • Open SimpleSYN on the client.
  • Go to "Options" and make sure:
    • "Default" is selected for "Login."
    •  In the "Password" field, enter the new password you assigned on the server.
    • Save the settings.

Open the SimpleSYN main window> Options> advanced options on the PC.

Check the box next to "Enable Outlook Add-In" and save the page.

Then restart SimpleSYN.

Otherwise, check once in Outlook under File> Slow and deactivated COM add-ins whether in this area the add-in has been deactivated and reactivate the add-in if necessary.

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.
