Webinhoud in Outlook 2007 en 2010
Voordat Microsoft Office 2007 er was, werden e-mails -die als webpagina waren opgemaakt- redelijk goed weergegeven in Outlook.
Outlook gebruikte voor het weergeven van webinhoud namelijk het mechanisme van de webbrowser Internet Explorer 6.
Vanaf Office 2007 heeft Microsoft in haar goddelijke wijsheid echter besloten om web-mails binnen Outlook voortaan door Word te laten weergeven.
Word is echter een tekstverwerker en haar HTML-mogelijkheden dateren van 2003!
Het gevolg is dat Outlook 2007 en 2010 webinhoud nog maar héél beperkt ondersteund en weergeeft.
Onder andere de volgende BASALE zaken worden niet meer ondersteund:
- CSS positionering en 'floats'
- CSS marges
- HTML formulieren
- HTML en CSS achtergrondafbeeldingen
- plugins (waaronder Flash)
- animated GIFs
- accessibility / toegankelijkheid support voor bijvoorbeeld slechtzienden

Hieronder echter al een uittreksel van die pagina met de lijst van zaken die niet meer ondersteund worden...
