I have a parent and child sites which I need to sync calendars. I
have a master on one site, and I want specific events to be displayed on the child site, but not every event.
I have a column already set up which filters events by this. I do not have access to all of the site, as this is a high-security company, so I cannot create a template. I do need each site to be able to add events, and have it automatically update all calendars linked.
Site A is the master and Site B receives events labeled for site B. If someone were to create an event on Site B in their calendar, I need it to also update on Site A.
How do I accomplish this? I have already tried Web parts and content query parts. Content queries did not work, and web parts worked for a while but stopped displaying events.
