2.2.71 [RFC5545] Section 3.8.3.1 Time Zone Identifier

  • Article

V0136:

The specification states that non-standard property parameters can be specified on the TZID ([MS-OXCICAL] section 2.1.3.1.1.19.1) property.

Microsoft Exchange Server 2007, Microsoft Exchange Server 2010, Microsoft Exchange Server 2013, Microsoft Exchange Server 2016, Microsoft Exchange Server 2019

Microsoft Exchange Server does not export any parameters on the TZID property. On import, Microsoft Exchange ignores all parameters on the TZID property.

V0137:

The specification states that the TZID property MUST be specified in a VTIMEZONE component.

Exchange 2007, Exchange 2010, Exchange 2013, Exchange 2016, Exchange 2019

Microsoft Exchange exports exactly one TZID property in a VTIMEZONE component. On import, Microsoft Exchange fails to import iCalendar objects with any VTIMEZONE without a TZID property. If multiple TZID properties are specified within a VTIMEZONE, Microsoft Exchange ignores all but the last.

V0138:

The specification states that the presence of a SOLIDUS character as a prefix indicates that the TZID represents an unique ID in a globally defined time zone registry.

Exchange 2007, Exchange 2010, Exchange 2013, Exchange 2016, Exchange 2019

Microsoft Exchange does not export TZID properties with a SOLIDUS prefix. On import, Microsoft Exchange performs no special handling of TZID properties prefixed with a SOLIDUS character.

V0139:

The specification states "This document does not define a naming convention for time zone identifiers. Implementers may want to use the naming conventions defined in existing time zone specifications such as the public-domain Olson database [TZ]. The specification of globally unique time zone identifiers is not addressed by this document and is left for future study."

Exchange 2007, Exchange 2010, Exchange 2013, Exchange 2016, Exchange 2019

On export, Microsoft Exchange relies on the operating system for time zone names. On import, Microsoft Exchange makes no assumptions regarding the naming convention used to name a time zone in the TZID property.
