Today I was trying to send a message via the platform to the people who have RSVPd for a couple of SAP CodeJams that I will be running in Zagreb, Croatia (Integration Suite, btp CLI) next week and I was getting the infamous invalid HTML error when drafting the message. Sometimes the platform auto-magically fixes the issue but in this case, I was still getting the message. When inspecting the HTML, I noticed an additional tag that I’d not seen before in an HTML a tag. So, whenever you face this issue, check for any odd attributes that you might find in your HTML.

- Problem: I originally copied the message from Outlook and the hyperlinks (a tags) includes the additional attribute - data-outlook-id.
- Solution: This attribute data-outlook-id was causing the issue. Remove it from the HTML and it works fine.
