JIRA Service Desk - Notification email display problem on Outlook

Hello,

On the customer portal, when the request forms include the character '/', the notification email that is sent after the ticket is created is not displayed correctly on Outlook (see screenshot), however it works correctly from other email boxes (gmail).
