How long does it take for an exchange transport rule to take effect?

Okay, so you're wondering how long it takes for those Exchange transport rules to actually kick in, right? I remember the first time I messed with those things, I was constantly refreshing everything, thinking I'd messed something up!

Basically, you're looking at up to 30 minutes for any changes you make to those Exchange transport rules to fully propagate and, you know, actually start working. Think of it like this: it's not instant! Sometimes it feels like forever, especially when you're trying to fix a critical issue, doesn't it? I mean, half an hour can feel like an eternity when emails are misbehaving!

So, yeah, give it that 30-minute window. Grab a coffee, maybe double-check your settings to make absolutely sure you didn't typo something (we've all been there!), and then test it again. Hopefully, it'll be behaving as expected by then. And if not, well, that's when the real troubleshooting begins, eh? Good luck with it!
