Identified
We are seeing `ErrorInternalServerError` API errors from a small number of Microsoft grants when attempting to create new events or new calendars in the Nylas API.
We have confirmed that these errors are coming from Microsoft Graph API email servers and have reached out to Microsoft to address this issue.
Additionally, if you retry a failed API call to create a new calendar, a different error 409 `ErrorFolderExists` may be returned. This error is also from Microsoft Graph API.
This does not appear to be affecting any on-premise Exchange (EWS) grants or other email providers.
