2.2.58 [RFC5545] Section, Description


The specification states that non-standard, alternate text representation, and language property parameters can be specified on the DESCRIPTION property.

Microsoft Office Outlook 2007, Microsoft Outlook 2010, Microsoft Outlook 2013, Microsoft Outlook 2016, Microsoft Outlook 2019

Outlook does not export parameters on the DESCRIPTION property.

On import, Outlook only uses the first LANGUAGE parameter found in a SUMMARY, LOCATION, or DESCRIPTION property of a VEVENT component. In all other cases, parameters on the DESCRIPTION property are ignored.


The specification states that the DESCRIPTION property can be specified within the VEVENT, VTODO, VJOURNAL, or VALARM components, and may be specified multiple times in a VJOURNAL component.

Office Outlook 2007, Outlook 2010, Outlook 2013, Outlook 2016, Outlook 2019

Outlook can export at most one DESCRIPTION property on a VEVENT component. Outlook exports exactly one DESCRIPTION property on a VALARM component, and the value is "Reminder". Outlook does not export a DESCRIPTION property for any component other than a VEVENT or VALARM.

On import, if multiple DESCRIPTION properties are present in a VEVENT component, then Outlook ignores all but the first. Outlook ignores DESCRIPTION properties on any component other than a VEVENT.
