Monitoring Event sink # 6 - Using Store Event Sink Bit Flags

  • Comments 2
 
In Event sink development, we have event sink bit flags. These flags can be used to identify which event sink was fired.
 
The bit flags are implemented in EXEVTSNK.TLB, which is installed with the Exchange Software Development Kit (SDK). Then these flags are passed through the LFLAGS parameter of the following Exchange store event interface methods:

Event Sink Flags Hexidecimal Value Decimal Value Description
EVT_NEW_ITEM 0x00000001 1 The item is newly created.
EVT_IS_COLLECTION 0x00000002 2 The item is a folder.

EVT_IS_DELIVERED 0x00000008 8 The item is being saved as a result of message delivery.
EVT_SOFTDELETE 0x00000010 16 The item was deleted.
