2.2.2.22 Exceptions

The Exceptions element is an optional container ([MS-ASDTYPE] section 2.2) element that specifies a collection of exceptions to the recurrence pattern of the calendar item. It is defined as an element in the Calendar namespace and is used in ActiveSync command requests and responses as specified in section 2.2.2.

The Exceptions element can have the following child element:

• Exception (section 2.2.2.21): This element is optional.

Protocol Versions

The following table specifies the protocol versions that support this element. The client indicates the protocol version being used by setting either the MS-ASProtocolVersion header, as specified in [MS-ASHTTP] section 2.2.1.1.2.6, or the Protocol version field, as specified in [MS-ASHTTP] section 2.2.1.1.1.1, in the request.

Protocol version	Element support
2.5	Yes
12.0	Yes
12.1	Yes
14.0	Yes
14.1	Yes
16.0	Yes
16.1	Yes

The client MUST NOT include the Exceptions element in a Sync command request ([MS-ASCMD] section 2.2.1.21) to change an exception when protocol version 16.0 or 16.1 is used. Instead, the client includes the airsyncbase:InstanceId element ([MS-ASAIRS] section 2.2.2.25) along with the airsync:ServerId element ([MS-ASCMD] section 2.2.3.166.8) to change an exception.

In protocol version 16.0 and 16.1, changing the recurrence pattern or the start/end times of a recurring series will delete any exceptions present on the calendar item.
