Monitoring
Microsoft has started to recover from the Microsoft 365 outage that began yesterday around 12:30pm ET. We are now turning Outlook sync back on in stages to avoid overloading our sync systems. Outlook emails and calendar events from the outage will sync in automatically as each account catches up, and nothing needs to be reconnected. Gmail and Google Calendar sync are working normally. We will post another update once Outlook sync is fully restored.

Identified
Gmail and Google Calendar syncs are back to normal. Outlook email and calendar syncs are paused on our side while Microsoft's Exchange Online outage continues, so new Outlook emails and meetings will not show up in Vitally until Microsoft recovers. No data is lost. Once Microsoft resolves their issue, we will turn Outlook syncs back on and they will catch up automatically. We will post another update then.

Identified
We are seeing delays syncing emails and calendar events from connected Outlook and Gmail accounts. This is caused by an ongoing Microsoft 365 outage affecting Exchange Online. Outlook data is delayed by up to about 2 hours, and Gmail and Google Calendar are delayed as well while the sync queue catches up. No data is lost. Syncs will catch up automatically once Microsoft resolves their issue. We will post an update when things are back to normal.
