My company used outlook calenders, displayed in an iframe in the old website to give customers up-to-date information on our booking.
On the old website, as of a week ago, they blanked out. I figured this had something to do with the update, but inserting them with a web part gives the same blank. I can link to them, so the link works, and permissions are open, but nobody can see the calenders.
What am I missing? Anyone successfully done this?
