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.

• 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.
