2.2.59 [RFC5545] Section 126.96.36.199, Geographic Position
The specification describes the GEO property.
Microsoft Office Outlook 2007, Microsoft Outlook 2010, Microsoft Outlook 2013, Microsoft Outlook 2016, Microsoft Outlook 2019
Outlook does not implement the GEO property. Outlook does not export or import this property.
The specification does not explicitly state that implementing this property is required. It states: "This property can be specified in 'VEVENT' or 'VTODO' calendar components." Later, it states: "The longitude and latitude values MAY be specified up to six decimal places, which will allow for accuracy to within one meter of geographical position. Receiving applications MUST accept values of this precision and MAY truncate values of greater precision."
Office Outlook 2007, Outlook 2010, Outlook 2013, Outlook 2016, Outlook 2019
The phrase "receiving applications MUST accept values" is interpreted as being required contingent on actually implementing this property. The phrase "this property can be specified" is interpreted to mean that the property is optional.
