SimpleSYN Mobile version history
Version 2.5 (Build 12321) released 3/22/2024:
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.
Minor bug fixes and optimizations.
Version 2.3 (Build 11920) released 11/20/2023:

Deleting a device's sync status may only work if sync was manually disabled in advance.
The "Configuration" page has been improved when using a large number of user accounts.
Version 2.2 (Build 11818) released 10/18/2023:
When SimpleSYN Mobile and the sync process are running as administrator, the sync process was not detected as started. The status display of the end devices was also not available. Note: We recommend that you do not run SimpleSYN and Outlook as administrators for security reasons.
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".
NEW: Birthdays from contacts can be skipped when synchronizing the calendar. This prevents the birthdays from being duplicated in iOS and other calendar apps.
NEW: Contains the Outlook add-in known from SimpleSYN with additional functions:
Restore Deleted Items: Allows you to restore items that were deleted during synchronization.
Find duplicates: Searches an Outlook folder for duplicates and similar items and allows you to quickly clean up found duplicates.
NEW: The synchronization status of devices can be deleted.
Improved: Deleted items backed up during synchronization can be automatically deleted after a configurable period of time.
Improved: The options on the configuration page have been better arranged.
Improved: Allows to start without user login and without specifying a Windows password.
Improved: The configuration of the advanced options now directly shows the required changes to the Windows configuration. The adjustments can be made quickly with one click.
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". This makes it possible to circumvent display problems on some systems, especially when accessed via remote maintenance software.
Improved: Deleted folders no longer appear under "Devices".
Improved: The product ID in the "About" dialog can now be copied.
Improved: When creating error reports, the path can now be copied.

Fixes an error when replying or forwarding an email. If the replied or forwarded email contained an invalid HTML body, the new email failed to be sent.
Version 1.6 (Build 11402) released 6/19/2023:
Existing meeting invitations in a calendar folder that is not the default calendar can now be answered. Note: If an meeting invitation is received by email, the default calendar must also be selected for synchronization. Otherwise, an error message will appear on the device when answering meeting requests.
New major versions can be installed from within the program in the future, provided that the license is valid for the newer version (e.g. subscription).
Version 1.5 (Build 11203) released 4/3/2023:
