Version 5.0 (Build 13126) released 11/26/2019:
  • Fixes an incorrect notification of unresolved conflicts, even if there is no need to resolve conflicts.
  • Fixes an error while loading the folder hierarchy, if sub folders are not supported.

Version 5.0 (Build 12823) released 8/26/2019:

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:

Version 5.0 (Build 12711) released 7/12/2019:

  • 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.
