Inactive in Current Organization

This Condition located on the Current org category tab in Search Builder is used internally for some Convert to Search type of searches. However, you can use it, too.

It will find everyone who is currently an Inactive Member in the last organization you viewed. You can also just look at the Inactive tab of the org itself. However, if you want to combine this with another Condition such as Church Member Status or something else, then this Condition is helpful.
