SimpleSYN Desktop version history

Version 5.0 (Build 12812) released 8/15/2019:
  • Fixes a crash when Outlook is returning an unexpected error.
Version 5.0 (Build 12806) released 8/7/2019:
  • NEW: Improves the performance when starting SimpleSYN.
  • NEW: Improves the mapping of items during initial synchronization.
  • Resolves a possible crash due to errors in third-party MAPI datastores.
  • Resolves a very rare connection problem that could cause SimpleSYN to hang with 100% CPU usage.
  • Smaller bug fixes and tweaks.
Version 5.0 (Build 12711) released 7/12/2019:
  • NEW: Improved initial synchronization between different versions of Outlook. For example, different separators in messages, or incorrectly formatted links, are handled better, eliminating duplicates during initial synchronization.
  • NEW: After SimpleSYN starts, the folder hierarchy is always transferred once to synchronize changes to it more quickly.
  • NEW: Subject line prefixes are now transferred separately to correctly represent custom values. Custom prefixes also could have lead to duplicates when a resynchronization takes place.
  • Improves error handling for custom Outlook data fields that cannot be resolved. As a result, synchronization may have stopped and continued incorrectly.
  • Resolves an issue if the synchronization state on the server has been deleted. If only a few items were synchronized once, the client did not recognize the required resynchronization and the synchronization was performed incorrectly.
Version 5.0 (Build 12621) released 6/24/2019:
  • Improves reliability when importing items with unexpected data
Version 5.0 (Build 12614) released 6/14/2019:
  • Fixes an error while deleting data fields. This error led to faulty synchronization with Outlook version 1906 (Build 11727.20104) and newer
  • Fixes an error when enabling or disabling the Outlook add-in via "advanced options"
Version 5.0 (Build 12613) released 6/13/2019:
  • Fixes a problem that date values greater than 12/31/9999 23:59:59.9 could cause a crash or a cancellation of the synchronization
  • Fixes a crash that could occur due to incorrect error handling when accessing Outlook items
  • Fixes a discontinuation of synchronization if an attachment could not be synchronized correctly
  • Smaller bug fixes and tweaks
Version 5.0 (Build 123604) released 6/4/2019:
  • NEW: Improves the reliability of the connection when using IPv4 and IPv6 simultaneously
  • NEW: Improves support for local proxy servers such as Fiddler
  • Fixes an error that could lead to a disconnection if the connection used an relay server
  • Fixes an error when closing a relayed network connection
  • Fixes a problem that an unexpected data type within an Outlook item may cause an interruption of the synchronization
  • Fixes a problem that leads to no data file being available for the synchronization, if the Outlook profile contains an error
  • Removes a misleading log entry
Version 5.0 (Build 12526) released 5/26/2019:
  • Fixes the error handling for invalid Unicode characters. Invalid characters could have caused a folder to stop synchronizing.
Version 5.0 (Build 12523) released 5/23/2019:
  • Fixes an error that could lead to an invalid sync status if a pre-copied PST file was used on both computers. In this case, it was no longer possible to synchronize.
  • Fixes a recovery synchronization error with new items. In rare cases, it could have happened that one element was assigned to a deleted item on the other side and subsequent synchronization of that element was no longer possible.
  • Fixes a wrong configuration parameter in the SimpleSYN Windows service, which prevents SimpleSYN from starting automatically with Windows.
  • The standard Outlook data file is again correctly labelled as such in the user interface.
  • A poorly scaled status indicator on high-resolution monitors on the server side has been corrected.
  • Fixes an error when items are deleted from the synchronized folder during synchronization.

SimpleSYN Mobile version history

Version 2.6 (Build 12417) released 4/26/2024:
  • Fixes a compatibility issue with Samsung apps and improves the reliability of the synchronization in general.
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.

  • Fixes an issue that prevented a retrial period when upgrading from version 1 to version 2.
    If you have purchased a lifetime license for SimpleSYN v1, you can now test it again free of charge for a full 30 days after installing v2.
  • 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.

Version 1.7 (Build 11506) released 7/10/2023:
  • 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.
