Is there a way to add a popup about the size limit of email content when it exceeds ?

Hi All,

When the email body reaches the maximum size, the email was not sent out with the error message as "552 5.3.4 message size exceeds fixed maximum message size". So is there a way to add a popup about the size limit of email content when it exceeds the defined message size while sending the email from compose email option in ServiceNow.

Thanks!

Ramkumar

@Ramkumar Thanga

you can show an alert when compose email opens that popup

check this KB for message you want to show

Email server size limit prevents emails from being sent or received

Create this new UI script

addLoadEvent(hideButtonsAdd);

function hideButtonsAdd() {
    if (document.URL.indexOf('email_client.do') != -1) {
        alert("Please don't exceed 10MB email size"); // give your message here
    }
}

Output:

If my response helped please mark it correct and close the thread so that it benefits future readers.
