If you set up the SimpleSYN Mobile account on the mobile device and made a mistake when entering the e-mail address or the password, there will be no error message with the old Android versions, but the settings are incomplete and synchronization cannot take place.

Make sure that "Server" displays a longer string of numbers and letters, followed by "".

If only"" is displayed in "Server", you probably have typed in a wrong email address or password. In this case, tap the back arrow and check the email address and password details.

If you want to make a backup of your Outlook data files, disable the synchronization of SimpleSYN Mobile and close the main window. SimpleSYN Mobile then no longer accesses the data files. After the backup, you can re-enable synchronization.

To deactivate the synchronization, right-click on the SimpleSYN Mobile icon in the notification area and select "Disable synchronization" from the context menu.

On the Windows PC, the Outlook data file must be selected in the SimpleSYN Mobile main window under "Configuration" and here the "Contacts" and the "Calendar" must be selected for synchronization.

The SimpleSYN Mobile calendar or contacts must be selected on the Android device and the entry "Synchronize contacts" and "Synchronize calendar" must also be activated in the account settings for the SimpleSYN Mobile account (see example below).

Category: Version 1.0

For setting up the synchronization on the device, a special SimpleSYN Mobile account of the type "Exchange ActiveSync" is created.

During the first synchronization, the data is synchronized from Outlook to the mobile device. Changes made in this account after the first synchronization are always synchronized by SimpleSYN Mobile to both sides (bidirectional).

E-mails, appointments and contacts that were saved on the mobile device before the first synchronization, i.e. that are not in the SimpleSYN account, are not synchronized to Outlook because they use different accounts. If you also want to keep this data up to date in the future, make sure that this data is also available in Outlook before the first synchronization.

If you want to sync multiple Outlook data files, create a separate user account for each Outlook data file. Multiple user accounts are also suitable for synchronizing different mobile devices (e.g. iPhone and iPad) with separate settings.

You can manage the user accounts individually and select which folders to synchronize for each user. Thus, it is possible to synchronize, e.g., on the iPhone only the Outlook calendar and on the iPad additionally to synchronize the contacts.

With SimpleSYN Mobile, you can not only sync your emails, contacts, and calendar to your smartphone, but also sync the notes and tasks.

However, Android devices do not have a built-in default app for managing notes. On your Android device, you must therefore use a third-party app, such as "Tasks & Notes for MS Exchange" ( You can use the current Gmail app for the tasks.

On your iOS device, you do not need an additional app and you can use the built-in tasks and notes apps.

Category: Version 1.0

There is usually no need to install an additional app on your mobile device. For setting up the synchronization on the device, a special SimpleSYN Mobile account of the type "Exchange ActiveSync" is created.

Before SimpleSYN Mobile can be used for synchronization, you must set up SimpleSYN Mobile once, configure the devices you want to synchronize and connect them to SimpleSYN Mobile.

The setup process therefore includes two steps:

  1. Installing and setting up the SimpleSYN Mobile software on your Windows ® PC with Outlook ® installed.
  2. The configuration on your devices (e.g. smartphone).

During setup on the PC, a SimpleSYN Mobile pseudo email address is automatically generated. The address has the ending and is required to establish a connection from your device.

You can find more information about the setup on this page.
