From Synergration developer of Contact Sync:

Hi Bill,

Unfortunately, we stopped supporting that software some time ago.  Officially Intuit, having integrated it into QuickBooks many years ago, agreed to handle primary support however we helped solely because they generally failed to.

I sincerely wish I could be of more assistance.

Is there any fix for this available yet? I am running Quickbooks Desktop Pro 2019 and Outlook 365. The add-in installs but I get the same error message about the revoked certificate. I just got a new desktop and migrated all my programs and files over from my old computer, but I swear the Sync worked just fine with the same software setup on my old one but just doesn't seem to work now.
