Redundancy in Query

Hi,
If you use !has it will be more performant than !contains. In case UserId values like person@email are the full values and not partial ones you can do this:
OfficeActivity
| where UserId !in~ ("person@email","another@email","user@email")
!in~ should also be more efficient than !contains. Let me know if this answers your question.
