Hi, @TomCruise-7376
It sounds like you're looking to create more complex exceptions to your email flow rules.
You're right. In Exchange Online, exceptions in mail flow rules are typically connected via OR rather than AND. This means that if any of the exceptions are met, the rules will not apply. The best indirect way to implement this logic is if you want to turn an exception into an AND relationship, you can create multiple rules to achieve a similar effect.
For example, you can create two rules, the first one checking the first condition and the second rule checking the second condition. The transport rule is applied only if neither rule is satisfied.
