SimpleSYN Mobile version history

Version 2.4 (Build 12214) released 2/14/2024:

    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.

  • Fixes an error when synchronization reply-to email recipients in the x64 version.
  • Fixes a possible vulnerability in the SimpleSYN installer component.
