We have been trying to include an MP4 file in our replies to customers via Jira service tickets. However, when we add the MP4, the customer’s email shows a message at the bottom stating that the resource cannot be embedded, which prevents the customer from downloading the MP4.
When searching in Jira, we found some information indicating that MP4 files may not be supported in customer notification emails, either as attachments or as links. Another source suggests that it should work as long as we adjust the attachment-related settings in the customer notification configuration. The relevant information is shown in the screenshots below.
Could you please advise which information we should follow? Specifically, we would like to confirm whether, under our current Jira Service configuration, MP4 files indeed cannot be included in customer notification emails. Thank you.
