2.2.48 [RFC5545] Section 3.6.6, Alarm Component

V0059:

The specification states that the ACTION property is required on VALARM components, and describes the possible values of the ACTION property of the VALARM component. The possible values specified are "AUDIO", "DISPLAY", "EMAIL", and "PROCEDURE". The format for the VALARM component is specified for each possible value of the ACTION property.

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

Outlook only exports VALARM components with the ACTION property set to "DISPLAY". The other types ("AUDIO", "EMAIL", and "PROCEDURE") are not implemented by Outlook.

On import, Outlook ignores the ACTION property of the VALARM component. All VALARM components are treated as a reminder ([MS-OXORMDR]).

V0060:

The specification states that the TRIGGER property is required on VALARM components.

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

Outlook ignores any VALARM components that do not have a TRIGGER property.

V0061:

The specification states that the DURATION and REPEAT properties are optional on VALARM components.

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

Outlook does not export DURATION or REPEAT properties on VALARM components. On import, these properties are ignored on VALARM components.

V0062:

The specification states that the ATTACH property is optional for VALARM components that have the ACTION property set to "AUDIO" or "EMAIL", and is required for VALARM components that have the ACTION property set to "PROCEDURE".

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

Outlook does not implement VALARM components with the ACTION property set to "AUDIO", "EMAIL", or "PROCEDURE". Outlook does not export the ATTACH property on VALARM components. On import, this property is ignored on VALARM components.

V0063:

The specification states that VALARM components can optionally have additional x-prop properties set on them.

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

Outlook does not export any x-prop properties on VALARM components. On import, any x-prop properties on VALARM components are ignored.

V0064:

The specification states that the DESCRIPTION property is required for VALARM components with the ACTION property set to "DISPLAY" or "EMAIL", and optional for VALARM components with the ACTION property set to "PROCEDURE".

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

On import, Outlook ignores the DESCRIPTION property.

V0065:

The specification states that the SUMMARY property is required for VALARM components with the ACTION property set to "EMAIL".

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

Outlook does not export VALARM components with the ACTION property set to "EMAIL". Therefore, it does not export the SUMMARY property on VALARM components.

On import, Outlook ignores the SUMMARY property.

V0066:

The specification states that the ATTENDEE property is required for VALARM components with the ACTION property set to "EMAIL".

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

Outlook does not export VALARM components with the ACTION property set to "EMAIL". Therefore, it does not export the ATTENDEE property on VALARM components.

On import, Outlook ignores the ATTENDEE property.

C0004:

The specification states, "When the action is 'AUDIO', the alarm can also include one and only one 'ATTACH' property, which MUST point to a sound resource, which is rendered when the alarm is triggered." It is unclear whether "which is rendered when the alarm is triggered" is a normative requirement.

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

This is interpreted as a recommendation, not a requirement. Outlook ignores the ATTACH property on VALARM components.

C0005:

The specification states, "When the action is 'DISPLAY', the alarm MUST also include a 'DESCRIPTION' property, which contains the text to be displayed when the alarm is triggered." It is unclear whether "to be displayed when the alarm is triggered" is a normative requirement.

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

This is interpreted as a recommendation, not a requirement. On import, Outlook ignores the DESCRIPTION property on VALARM components.

C0006:

The specification states, "When the action is 'EMAIL', the alarm MUST include a 'DESCRIPTION' property, which contains the text to be used as the message body, a 'SUMMARY' property, which contains the text to be used as the message subject, and one or more 'ATTENDEE' properties, which contain the email address of attendees to receive the message. It can also include one or more 'ATTACH' properties, which are intended to be sent as message attachments. When the alarm is triggered, the email message is sent." It is unclear whether "when the alarm is triggered, the email message is sent" is a normative requirement.

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

This is interpreted as a recommendation, not a requirement. On import, Outlook ignores the DESCRIPTION, SUMMARY, ATTENDEE, and ATTACH properties. Outlook does not send e-mail messages when alarms are triggered.

V0067:

The specification states that VALARM components must only appear within VEVENT or VTODO components.

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

Outlook only exports VALARM components within VEVENT components. On import, any VALARM components found outside of a VEVENT component are ignored.

V0068:

The specification states that multiple mutually independent VALARM components can be specified for a single VEVENT or VTODO component.

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

Outlook only exports at most one VALARM component per VEVENT component. On import, Outlook uses the first VALARM component with a valid TRIGGER property found in a VEVENT component. All other VALARM components within that VEVENT are ignored.

V0069:

The specification states that the TRIGGER edge may be explicitly set to be relative to the START or END of a VEVENT or VTODO with the RELATIVE parameter on the TRIGGER property.

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

Outlook does not export or import the RELATIVE parameter of the TRIGGER property.

V0070:

The specification states that the TRIGGER property can alternatively be set to an absolute calendar date and time of day value.

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

Outlook does not export the VALUE parameter of the TRIGGER property. On import, if the value of the TRIGGER property is not a DURATION type as specified in [RFC5545] Section 3.3.6, then Outlook ignores the VALARM component.

V0071:

The specification states that, if an alarm is set to trigger on the START of an event or to-do, then the DTSTART property MUST be present in the associated event or to-do.

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

On import, Outlook can successfully parse the event or to-do if there is no DTSTART property. For more details, see section 2.2.70.

V0072:

The specification states that, if an alarm is set to trigger on the END of an event, then either the DTEND property MUST be present, or the DTSTART and DURATION properties MUST both be present.

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

On import, Outlook can successfully parse the event even if DTEND and DURATION are both missing. For more details, see section 2.2.70.

V0073:

The specification states that an alarm in a VTODO component that is set to trigger on the END of the to-do either MUST have the DUE property, or MUST have both DTSTART and DURATION.

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

Outlook does not export or import VTODO components.

V0074:

The specification states that an alarm can be defined such that it triggers repeatedly, using the DURATION and REPEAT properties on the VALARM component.

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

Outlook does not export repeating alarms. On import, Outlook ignores the DURATION and REPEAT properties on VALARM components.

V0075:

The specification states that it is typically the responsibility of the Calendar User Agent to deliver the alarm in the specified fashion.

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

On import, Outlook ignores the ACTION property on VALARM components. All VALARM components are treated as a reminder ([MS-OXORMDR]).

C0008:

The specification states, "In an AUDIO alarm, if the optional 'ATTACH' property is included, it MUST specify an audio sound resource. The intention is that the sound will be played as the alarm effect. If an 'ATTACH' property is specified that does not refer to a sound resource, or if the specified sound resource cannot be rendered (because its format is unsupported, or because it cannot be retrieved), then the CUA or other entity responsible for playing the sound may choose a fallback action, such as playing a built-in default sound, or playing no sound at all." It is unclear whether "the intention is that the sound will be played as an alarm effect" is a normative requirement.

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

This is interpreted as a recommendation, not a requirement. On import, Outlook ignores the ATTACH property on VALARM components.

C0009:

The specification states, "In a DISPLAY alarm, the intended alarm effect is for the text value of the 'DESCRIPTION' property to be displayed to the user." It is unclear whether "the intended alarm effect is for the text value of the 'DESCRIPTION' property to be displayed to the user" is a normative requirement.

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

This is interpreted as a recommendation, not a requirement. On import, Outlook ignores the DESCRIPTION property on VALARM components.

C0010:

The specification states, "In an EMAIL alarm, the intended alarm effect is for an email message to be composed and delivered to all the addresses specified by the 'ATTENDEE' properties in the 'VALARM' calendar component. The 'DESCRIPTION' property of the 'VALARM' calendar component MUST be used as the body text of the message, and the 'SUMMARY' property MUST be used as the subject text. Any 'ATTACH' properties in the 'VALARM' calendar component SHOULD be sent as attachments to the message." It is unclear whether "the intended alarm effect is for an email message to be composed and delivered to all the addresses specified by the 'ATTENDEE' properties in the 'VALARM' calendar component" is a normative requirement.

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

This is interpreted as a recommendation, not a requirement. On import, Outlook ignores the DESCRIPTION, SUMMARY, ATTENDEE, and ATTACH properties. Outlook does not send e-mail messages when alarms are triggered.
