Release Date: 8/7/2019

• 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.

• 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.
