How to Fix Mimecast 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 regional routing: Mimecast routes traffic through different geographic regions. Switching your gateway to another region might bypass a localized server failure.
- Check sync connectors: Look at your Microsoft 365 or Exchange logs. A dropped connection on your local server might look like a Mimecast problem even if the main service is online.
- Test external DNS resolution: Open your command prompt and run a traceroute to the Mimecast gateways. If the request times out before reaching their servers, your local ISP might be the source of the failure.
