Zoom Room Calendar Integration migration

Hi All,

Some background - I have global admin rights in O365 at my company and administrate Zoom as part of my responsibilities. We have an existing setup with about 25 rooms on a working Calendar Resource but I must have logged in somewhere on accident using my own account and it switched the calendar resource to my account. Luckily, everything is still working but I'm trying to figure out how to move all the rooms back to the calendar resource. I tried adding a new resource and used the service account to set up. Moved one room over using the room settings but now it's saying "This calendar resource is no longer available in the calendar service." Room still looks like it's working but I'm afraid that come Monday, everything will be broken, so I'm hesitant to move the other rooms to this other Calendar Resource. Help!

My questions are - Is there a better way to migrate all the rooms to the correct calendar resource? Is there a way to change the resource from my account back to the service account without creating a new calendar resource? Is there a way to do it in bulk, or will I have to do this one by one? Did I totally screw up!? Any help would be greatly appreciated.
