I'm running the latest version of Windows 10 (10.0.19043), .Net Framework (1.1.4322), and Outlook 2010 (from Office Professional Plus 14.0.7015.1000). I installed Go Contact Sync mod, add my Google creds and Outlook profile, but when I sync I get a sync started message followed by: Error: Execution of authentication request returned unexpected result: 404. Can't find any references to this error in your support section.
Thanks,
Peter Denniston
