2.2.85 [RFC5545] Section 3.8.5.1 Exception Date-Times

V0183:

The specification states that the default value type of EXDATE is DATE-TIME, but it can be set to a DATE type.

Microsoft Office Outlook 2007, Microsoft Outlook 2010

On export, Outlook exports EXDATE as a DATE type if the recurrence is all-day. Otherwise, Outlook exports it as a DATE-TIME.

On import, Outlook can import EXDATE as either a DATE-TIME or DATE, provided the value falls on the same day as the original start date of an instance of the recurrence, in the recurrence's time zone.

V0184:

The specification states that non-standard, value data type, and time zone identifier property parameters can be specified on the EXDATE property.

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

Outlook exports the VALUE parameter on EXDATE if the value data type is DATE. Otherwise, Outlook exports the TZID parameter.

Outlook can export the TZID parameter on the EXDATE property. All other parameters are ignored.

V0185:

The specification states that the EXDATE property can be specified in an iCalendar object that includes a recurring calendar appointment.

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

Outlook only exports EXDATE in VEVENT components. Outlook ignores EXDATE instances outside of VEVENT components on import.

V0186:

The specification states that multiple instances of the RRULE and EXRULE properties can be specified to define more sophisticated recurrence sets.

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

See section 2.2.86 and section 2.2.88 for information regarding this statement.

V0187:

The specification states that the EXDATE property can be used to exclude the value specified in DTSTART. However, in such cases the original DTSTART date MUST still be maintained by the calendaring and scheduling system because the original DTSTART value has inherent usage dependencies by other properties.

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

Outlook can export EXDATE properties that correspond to the first instance of a recurrence. On import, Outlook can import EXDATE properties that correspond to the first instance of a recurrence. In this scenario, the original DTSTART is maintained.
