A transport rule doesn't behave as expected, another rule seems to override it
Exchange transport rules run in priority order. An earlier rule with 'stop processing' blocks later ones.
Try this first
- 1Open Exchange admin, sort transport rules by priority
- 2Check which rules have 'Stop processing more rules' enabled
- 3Reorder so specific rules sit above generic ones
- 4Use message trace to see which rule actually fires
