Monitoring
We're seeing a high number of errors from Office 365 accounts.
This is being reported on the Office 365 status page (https://status.office365.com/) as affecting the APAC and EMEA regions.
This will result in slower synchronization of events for affected Office 365 accounts. Once the problem is resolved within Office 365 our systems will ensure everything is made up-to-date.
