My Keyone continues to sync with Outlook.
Only issue I have is on occasion a contact that I modify in Outlook will update any note changes, but not name/address changes.
In the past I had to delete the account from my Keyone and reinstall it which fixed any issues. However I found a simpler solution that works for me – move the specific contact to a temp folder, wait for a sync (which deletes the contact from my Keyone) and then move the contact back into the Contacts folder and it will update on next sync.
