Hi Guys,\n\nI have a question. In my environment i want all people to use HTML format as standard in Outlook 2013. So when somebody forwards an email that is in plain text, i want him to send his mail in HTML, instead of plain text too.\n\nI installed an ADMX template for Outlook 2013 in my GPO and modified this setting:\nMicrosoft Outlook 2013/Outlook Options/Mail Format/Internet Formatting/ Message Format: Disabled.\n\nWhy Disabled? Because the gpo says: 'If you disable this policy setting, Outlook uses HTML as the default e-mail format and users will not be able to change it'. \n\nIt doesn't work. When i forward a plain text email, it changes my body and signature in plain text too.\n\nI found something on the internet for a registry setting for Editor Preference in HKCU\Software\Policies\Microsoft\Office\15.0\outlook\options\mail.\nI made a Editor Preference but i can't find the right decimal for it.\n\nCan somebody help me with this?
