Hi, I had about a dozen calendar events I needed to move into the future by a few months. I could not find instructions to move multiple calendar events, so I highlighted them in Lightening, cut, moved the calendar view to the desired date, and pasted them into the desired date. It worked, except it changed all of them from my original calendar to the native Lightening calendar. The original calender is a calender I synchronize with using the Provider for Google Calendar add-on. https://addons.thunderbird.net/en-US/thunderbird/addon/provider-for-google-calendar/ It seems like the same problem would occur if I had multiple calendars running within Lighting. How can one change the date of multiple calendar events and still have them assigned to their original calendar, please? Thanks, -SHD
