It appears that when an event is entered on an iphone 7 calendar it appears on the windows 10 calendar. The reverse does not happen;i.e., an event entered on the windows 10 calendar does not appear on the iphone 7 calendar. This was working up to a week or two ago. This is on a Dell XPS8900 desktop. An older Sony laptop with windows 10 appears to work as expected. Noted that the desktop calendar version is 17.8004.42017.0 while the laptop (that works) has calendar version 17.7992.42017.0 which I assume is an older version. Again, this worked on the desktop until a week or two ago. Suspect that the windows 10 mailtool got updated and that broke the process. Is there a fix?
