2.1.3.2.20 Auto Response Suppress

To generate an X-Auto-Response-Suppressheader (2), clients set the value of the PidTagAutoResponseSuppress property ([MS-OXPROPS] section 2.606).

When the PidTagAutoResponseSuppress property has a value of 0 (zero) or -1, MIME writers SHOULD<52> map its value to the X-Auto-Response-Suppress header (2) as shown in the following table.

PidTagAutoResponseSuppress property value

X-Auto-Response-Suppress header value

0

None

-1

All

When the PidTagAutoResponseSuppress property has a value other than 0 (zero) or -1, MIME writers MUST construct the value of the X-Auto-Response-Suppress header (2) as follows: For each bit of the value of PidTagAutoResponseSuppress that is set (left-hand column), append the string in the center column to the header value. If the header value was nonempty, append a comma (U+002C) and space (U+0020) before the new value.

0x00000020

Suppress auto-reply messages other than OOF notifications.

For example, if the value of the PidTagAutoResponseSuppress property is 0x000C, the header (2) MUST be written as follows:

X-Auto-Response-Suppress: RN, NRN

The order of these values in the header (2) is not important.
