IMAP accounts store your emails directly on your email provider's server. This means your emails are automatically synchronized across all your devices.

Important:
Since IMAP already automatically synchronizes email folders (such as Inbox, Sent Items), additional synchronization of these folders with SimpleSYN is not possible. This would lead to conflicts. Therefore, SimpleSYN does not display these email folders in the "Synchronization Settings" on the client.

 Even though email folders cannot be synchronized with IMAP, other local Outlook data such as:

  • Calendar
  • Contacts
  • Tasks
  • Notes

can be easily synchronized with SimpleSYN. 

If you also want your email folders to be synchronized via SimpleSYN, you should use a POP3 account on all PCs instead.

Category: Operation, Version 5.x, Version 6.x

When using the automatic synchronization it is also possible to synchronize all Outlook® subfolders automatically. The Outlook® subfolders will use the same synchronization direction and settings as their parent folder. Changes to the folder hierarchy below a selected folder are being synchronized.

Changes of the selected parent folder are not automatically synchronized. If a selected parent folder is being moved or deleted, the synchronization of this folder and all of its children will stop and is marked with a red X in the synchronization settings.

If you would like to continue synchronizing this folder at the new location, check the assignment of the folder in the synchronization settings on the client PC and save the page.

Moved subfolders are being deleted and completely resynchronized on the remote computer Deleted folders are also deleted on the remote side; all data inside the folder will be deleted in this case.

SimpleSYN is a Client-/Server application. In your SimpleSYN network one PC must be configured as a server. The SimpleSYN server must be authorized in the Windows Firewall and/or Desktop firewall.

Please make sure that SimpleSYN is allowed in your personal firewall.

SimpleSYN must communicate with our servers located at services.simplesyn.net.

SimpleSYN requires the following outbound TCP connections.

The trial versions of SimpleSYN Standard, Business, and Mobile offer the full range of features.

During the trial period, SimpleSYN Standard and Business will only display a notification window upon startup, indicating the remaining trial time, which you must manually confirm.

You can test SimpleSYN free of charge and without obligation for 30 days. After the trial period, further use without a license is no longer possible.

The SimpleSYN Business Version, in addition to all the features of the standard version, offers:

  • Synchronization over the Internet.
  • Filter function - for synchronizing certain Outlook items.
  • Windows service - start SimpleSYN automatically even if no user is logged on to Window.
  • Advanced synchronization options for reminders, categories and read status (version 6 and newer).

Category: Operation, Version 5.x, Version 6.x

If a computer is not reachable over network or Internet, then the synchronization is carried out as soon as the computer is back in the network or online and SimpleSYN has established a connection with the SimpleSYN server.

All Outlook items that were changed or created up to that point are automatically recognized and synchronized by SimpleSYN.

Category: Operation, Version 5.x, Version 6.x

The synchronization is not carried out in specific intervals, but rather as needed. As soon as the SimpleSYN client and SimpleSYN server have a connection the synchronization is carried out continuously and virtually in real-time.  After the initial synchronization only changes to the Outlook database are exchanged. The Outlook synchronization runs automatically in the background.

Example: If a new e-mail is received, an existing e-mail is changed, deleted of moved, SimpleSYN will immediately synchronize this action on all computers. SimpleSYN checks if the target folder already contains the e-mail. If the e-mail does not exist it is synchronized into the folder. If the e-mail already exists it will only be synchronized if a change has occurred. If the target computer is not reachable, the e-mail is synchronized as soon as the computer establishes a connection over the local network.

Licenses are offered as a one time payment. There are no additional costs per month/year. The license entitles you to use the licensed version (e.g. version 5.0). Minor updates (eg version 5.0 to version 5.0.1 etc.) are included. Major upgrades to new versions (eg version 5.x to version 6) are subject to a fee, but optional.

Category: Troubleshooting, Version 5.x, Version 6.x

Open the SimpleSYN options > advanced options and under “Outlook version” select your current Outlook version (2016 or 2013).  Save the settings and restart SimpleSYN.

If the behavior still occurs:

  • Please uninstall SimpleSYN on this computer from the Windows control panel > program/features and install SimpleSYN once again

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.
