  • For a contact user who is mail-enabled, you enable the Use MAPI Rich Text option on the Exchange Advanced tab in Active Directory Users and Computers.
  • A user sends an e-mail in HTML format to the contact.
In this scenario, the HTML format of the e-mail message is incorrectly converted to plain text when the contact user opens this e-mail message if Antigen 9.0 for Exchange is installed.
