Please check which major version of SimpleSYN Standard/Business you originally purchased.

If you purchased an older major version (e.g., version 6 or version 5), you probably have the current major version 7 installed. You can view the version number in the main window under "Information".

If this is the case:

Unfortunately, the old licenses are no longer valid for new major versions, hence the message.

You can set the default calendar on your iPhone so that new appointments are automatically assigned to the SimpleSYN Mobile account.

This means you no longer need to manually select the SimpleSYN Mobile account (@simplesyn.app) when creating new entries. Otherwise, the local calendar or the iCloud calendar is used as the default.

Here’s how to do it:

  1. Open the Settings app on your iPhone.
  2. Scroll down and tap Apps.
  3. Select Calendar.
  4. Scroll down and tap Default Calendar.
  5. Choose your SimpleSYN Mobile account (@simplesyn.app) as the default calendar.

From now on, all newly created appointments will automatically be assigned to the SimpleSYN Mobile account and synchronized with Outlook.

Category: Version 2.x / 3.x

If you create new entries on your smartphone - such as an appointment or a contact - please make sure to save them in the SimpleSYN Mobile account within the respective app (e.g., the Calendar app).

Ensure that the entries are not accidentally created in another account, such as the iCloud account (on iPhone) or the Google account (on Android devices), as they will otherwise not be synchronized.
