I currently find that I need to change the body content of the web version of a published email. OR I need to change the expiration date of said email (which luckily I put in place). But I can do neither. So, the current work around is to stop pointing people to that email all together. I’ll have to publish the information elsewhere or do another email with the new information and create a new web version.
Thankfully this now incorrect email will expire soon and I HIGHLY RECOMMEND if you are creating web versions of emails that you ALWAYS set them to expire.
