I've got a user in Office 365 who set up a calendar in her mailbox to be shared with others at her site. She's passed this calendar off to somebody else to manage, but since it was created on her mailbox, it's still attached to her. It's obvious that we should have set them up with a standalone shared calendar from the beginning, but that didn't happen...
Does anybody know of a way to convert just that calendar into a standalone shared calendar? I'm not seeing anything on it online.
