How a Mimecast Outage Halts Corporate Email Flow and Security Screening

Troubleshooting Steps When Mimecast is Not Working Today
If our page indicates that the service is operational, yet you are still asking "Why is Mimecast not loading?", try these quick troubleshooting steps:
- Verify Mimecast Services via the Administration Console: If you can still access the web portal, log in to the Mimecast Administration Console to check the Queue Directories. Look at the Rejection Queue and Delivery Queue to see if emails are piling up or being rejected with specific SMTP error codes, which indicates whether the Mimecast servers are actively rejecting your traffic.
- Switch to Mailbox Continuity Mode: If a confirmed Mimecast outage is blocking your primary mail flow, trigger your organization's Mimecast Continuity Event. This allows users to send and receive emails directly through the Mimecast Personal Portal or the mobile application, bypassing your on-premises or Microsoft 365 mail servers until the gateway recovers.
- Check MX Records and Gateway Routing: Run a dig or nslookup command on your domain's MX records to ensure they are pointing correctly to your designated Mimecast hostnames. If DNS resolution fails internally, flush your local DNS cache and test if you can telnet to the Mimecast SMTP servers on port 25 to rule out local firewall blockages.
