Troubleshooting Tip: License detected as invalid when uploading it to the FortiMail VM

[srahmat]

Description	This article describes how to resolve an issue where FortiMail using a subscription-based license informs the user that a license uploaded to the FortiMail VM is invalid.
Scope	FortiMail
Solution	This is only applicable for FortiMail using a subscription-based license. Run the command 'get system status'. It will show an error as below. A FortiMail subscription-based license is only supported for FortiMail firmware v7.0 and onwards. This issue happens because the FortiMail firmware version is lower than v7.0. To solve the invalid license issue, upgrade the FortiMail firmware to v7.0 and onwards.
