How do you test mail flow rules?

Okay, so you wanna know how to actually test those tricky mail flow rules in Exchange, huh? I get it. They can be a real pain to get right. Believe me, I've spent hours tweaking them, only to find out something weird happens when they go live. Ugh! Anyway, here's the lowdown on how I usually do it:

First things first, you gotta jump into the Exchange admin center (EAC). I mean, where else would you go, right? Once you're in there, you're gonna head over to the "Mail flow" section, and then "Rules." Easy peasy.

Now, you have a couple of choices. You can either tinker with a rule that's already kicking around, or you can create a brand new one from scratch. Honestly, sometimes I find it easier to just copy an existing rule and mess with the copy, just in case I completely break something... which, let's be real, has happened!

Alright, so you've got your rule open (or your new one created). This is where the magic happens! Look for the "Choose a mode" section. This is crucial. You'll see two options: "Test without Policy Tips" and "Test with Policy Tips."

Now, here's the difference, as I understand it:

• "Test without Policy Tips": This basically lets you see if the rule would apply without actually affecting anyone or throwing up any of those annoying policy tips for the sender. Think of it as a silent, behind-the-scenes check. This is super handy for catching those big, obvious errors before they become a problem.

• "Test with Policy Tips": Okay, this one's a bit more… interactive. It'll actually show the policy tips to the sender as if the rule was live. This is awesome for making sure those policy tips are clear, helpful, and not, you know, completely confusing. I remember one time, I had a policy tip that basically just said "Error," and I had no idea what it even meant! (facepalm). Testing with this option helps you avoid that kinda embarrassing stuff.

Basically, these testing options let you simulate the rule's execution before you unleash it on the unsuspecting masses. It's saved me from a lot of headaches, that's for sure! I even had a rule once that was supposed to flag external emails, but somehow ended up quarantining emails from my boss. Talk about a close call, and a good reason to test!
