Our corporate calendar is in Google Apps for Business, which I was connecting to via my WP8 phone. When I updated to WP10 this morning, when the new calendar app sync'ed it pinged every event in every calendar I have access to, triggering many thousands of "Event Changed" emails across the organization.
It's embarrassing, but not really catastrophic. What I really need to know is if the calendar app actually changed these events, or if they just got pinged.
Does anybody know?
