Google Calendar showing calendars that don't exist on my O365 account?

[dorlow]

So, I'm baffled right now. A few months ago, I cancelled my O365 account. I decided yesterday to open it back up. It was a brand new mailbox. (It's OK because I transferred all my email and appointments to gmail and then transferred them back.) I'm trying to use the Google Calendar to view my O365 calendar. The main calendar seems to be syncing just fine. I've verified logging into OWA, the calendars are not there. But, I'm showing calendars that I had on my old O365 account that doesn't exist on the new O365 account. I've tried to delete and re-add my O365 account in android settings. I deleted the data for the Google Calendar to force it to redownload everything. It keeps pulling down these calendars that don't exist in the mailbox.
