Remarks

This property may be left unset. If set, its value must be greater than "0x800186A0" (-2,147,383,648) and less than "0x7FFE7960" (2,147,383,648) and must be unique among tasks in the same folder.

Whenever the client sets this property to a number less than the negative of the current value of the PR_ORDINAL_MOST (PidTagOrdinalMost) property of the folder, the client must also update PR_ORDINAL_MOST on the folder.

The PR_ORDINAL_MOST property of the folder provides an efficient way to determine a unique value among tasks in the same folder.
