[Mailman-Users] Outlook Rich Text Format - Table and Embedded Links - Lost Format

Hi, One of my mailing list admins mentioned that when he sent out a Outlook email message with a table format that has embedded links. The table format disappeared and the embedded links don't show up as clickable. Some of mailing list admins like to send out postings with MS specific format and rather than plain text. Any suggestions on how they would be able to retain the MS Outlook format?

Please advise. Thanks Mary
