Office 365 - Old Calendar Events being sent from Office after enabling the plug-inn

After enabling the Microsoft Office 365 Extensions & APIs application, all my old events from zoho calendar started emailing to the participants from within Office 365.


As you can imagine this was not good.

Has anyone else experienced this?
Seems to be an issue with zoho?

We are working to sort this out and can't get to the root cause.
