HTML rendering

I am continuing with Outlook Support for the Outlook Internet standards compliance. Outlook 2007 was the first Outlook to switch from Internet Explorer HTML rendering to Microsoft Word 2007 HTML rendering. This means HTML and CSS items not handled by Word are no longer supported. On the other hand, HTML messages composed in Word will look more or less as they appeared to the author.

This most affects those publishing newsletters, because they frequently use intricate HTML and/or CSS to form their layout. For example, forms can no longer be embedded in e-mail.

Calendar compatibility

Outlook does not fully support data and syncing specifications for calendaring and contacts, such as iCalendar, CalDAV, SyncML and vCard 3.0. Outlook 2007 claims to be fully iCalendar compliant; however, it does not support all core objects, such as VTODO, VJOURNAL. Also, Outlook supports vCard 2.1 and does not support multiple contacts in the vCard format as a single file. Outlook has also been criticized for having proprietary "Outlook extensions" to these Internet standards. It supports offline storage files up to 2GB in size.
