HTML in email loops endlessly

[rbtroj]

We have a daily newsletter that goes out in HTML format through Salesforce. When read in Outlook, the body of the email just grows endlessly, repeating the html content over and over until Outlook crashes.



Sometimes a message eventually pops up saying "You have exceeded the maximum number of pages supported by Microsoft Office Outlook" if that helps anyone in determining a cause.

This has never been a problem until a day or two ago. I am checking with SF, but I wanted to check here too to see if anyone has encountered this before and if there are any known fixes.

Thanks!
