No Sync when outlook is open

Feb 9, 2016 at 10:00 AM
I get the error "Sync failed : Error Occurred" when I run the sync when the Outolook is open.
If I close the Outlook the Sync is ok.
I' using W10, the version of Calendar Sync + is 1.4.1.16 and the Outlook is Professional plus 2010, version 14.0.7165.5000 (23 bit)
