Troubleshooting Tip: FortiMail displays FEVM00UNLICENSED as serial number.

Verify License File: Validate that the license file matches the VM configuration.

Check CPU Allocation: Validate that the CPU value corresponds with what is indicated in the license file. FortiMail-VM01 requires exactly one CPU to function correctly.

Run the following via the CLI:

get system status

In this case, adjust the values of the VM to the value of the license.

Internet Connectivity: Confirm that the VM has internet access and can reach FortiGuard for license validation.
