The team completed remediating of the issue and we are currently monitoring.
The M365 Add In was impacted from 11:27-12:28 UTC.
Core Email Protection via API was impacted from 11:27-12:34 UTC. Emails during this window are currently being rechecked, so you may see a delay between email delivery and classification.
We will update once complete.
Investigating
Office Add-in checks are currently failing, the add-in will let emails send without checking, but with potentially increased latency.
Live Syncing is currently failing to process emails and Core Email Protection via API is currently failing to check emails.
