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.
The fix-up of distribution lists/contact groups will now make sure the selected contact is unique.
Fixes an error that caused the client to show "online", but no synchronization takes place.
Other optimizations and bug fixes.
Version 5.0 (Build 12823) released 8/26/2019:
Fixes an error in the folder hierarchy synchronization. If Outlook returned an internal error while opening a folder, it was possible that SimpleSYN deleted this folder accidentally instead of stopping the synchronization.
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.
Version 5.0 (Build 12517) released 5/17/2019:
Fixes an error during the recovery synchronization of a deleted item
Fixes an rare crash when handling Outlook events
Fixes an crash during initialization of folder monitoring
Fixes a rare crash during connection establishment
Fixes a wrong version number
Version 5.0 (Build 12515) released 5/15/2019:
Added some missing digital signatures
Fixes a crash when exiting SimpleSYN, that may occur when shutting down Windows
Fixes a rare crash when saving the SimpleSYN configuration
New Version 5.0 released 5/6/2019
NEW: Supports Outlook 2019 (Office 365)
SimpleSYN supports the latest Outlook generation, but remains downward compatible with the previous versions
NEW: Supports Outlook 365 from the Microsoft Store
SimpleSYN not only supports the normal Outlook installation version of Office 365, but also Office 365 installed from the Microsoft Store
NEW: Support for HTTP(S) Proxy Server
SimpleSYN can now be operated in networks that use HTTP (S) proxy servers
NEW: Advanced network settings
The network connections used by SimpleSYN can now be configured in the advanced options. In the advanced options it is also possible to activate a user-defined connection, for example to run SimpleSYN on local networks without an internet connection
NEW: Improved conflict resolution and conflict detection
Faster conflict resolution directly in the conflict list, as well as improvements in conflict detection
Improved performance Greatly improved performance during in the initial synchronization, as well as in the transmission of multiple elements
Improved synchronization Improved change detection, improved error handling, and improved detection of different synchronization states
Improved support for high resolution displays SimpleSYN has been optimized for displays with high DPI
Improved synchronization of distribution lists Distribution lists with many recipients are better supported
Improved selection of folders in the sync settings Default folders are now mapped, even if the folder names are different (for example, sent items <> sent objects)
Revision of how the filter works (business version) If the filter settings for an already synchronized folder change in the future, filtered-out items are not visible anymore for SimpleSYN and are considered a deletion
Optimized data transfer for changes
Improved export / import of data
Many other improvements and optimizations
