Fixes an issue when moving an item from one folder to another. This also applies to deleting an item from an device.
Version 2.4 (Build 12214) released 2/14/2024:
Changes behavior in the event of potential conflicts. If an item is changed in Outlook, simultaneous changes are now still applied by the end device, as long as no synchronized data fields have been changed. For any other change, conflict resolution is left to the end device. As a rule, this means that the changes are copied from Outlook and changes to the end device are overwritten.
Changes the behavior when an device sends unexpected or additional data fields. This data will now be ignored and the synchronization will continue. Previously, the synchronization of the affected item was rejected with an error.
Fixes an error when synchronization reply-to email recipients in the x64 version.
Fixes a possible vulnerability in the SimpleSYN installer component.
Changes of the available CALs are now applied in a more timely manny, without the need of a manual activation.

Version 2.1 (Build 11806) released 10/6/2023:
Addresses a compatibility issue that arises when using iOS 17, where certain appointments were displayed as meeting invitations instead of regular appointments. Note: If your appointments were erroneously synchronized, please disable calendar synchronization in your iOS device's account settings and then re-enable it.
New Version 2.0 released 9/8/2023
NEW: Version 2.0 is available to all subscription users at no extra cost. Users of the lifetime license of SimpleSYN Mobile 1.x are recommended to purchase an upgrade. If the current license is also valid for version 2, the new version will be installed automatically.
NEW: On the "Devices" page it is now shown whether a device is connected and synchronizing. The following states are distinguished:
1. Offline: Device is not connected and there is no data available when the device was last connected. The icon of the device is grayed out.
2. Online: It shows for several minutes that a device is connected or has been recently. The device's icon is displayed in blue, but changes to gray after 30 seconds.
3. Sync: While data is being transferred, the device icon is displayed in blue and with a sync animation.
4. Push Sync: If a device is connected and has activated push synchronization, the device icon is displayed in green.
In addition to the different device icons and colors, a text with identical status information is displayed.
NEW: Displays detailed messages about the status of the connection and error messages under "Information".

Improved: The status display of the synchronized data can be sorted.
Improved: The icon in the notification area is now also displayed in gray if the connection to the central servers does not exist. Previously, it only represented whether the sync process was executed.
Improved: Outlook no longer needs to be started to send e-mails so that e-mails can be sent immediately. Note: This requires the use of the default Outlook profile.
Improved: Performance has been optimized in many places.
Improved: A link to the privacy policy has been added under "Information".
Improved: Allows you to disable hardware acceleration of the UI, either via a setting under "advanced options" or via the command line parameter "/rendermode softwareonly".
