Set-ActiveSyncOrganizationSettings Exchange cmdlet issued (25358) how to monitor with email alert

[bob]

You know that event ID 25358 in the Event Viewer on Windows Server? It pops up when someone runs the Set-ActiveSyncOrganizationSettings cmdlet in Exchange. Basically, it logs that a change happened to your ActiveSync setup, like tweaking policies for mobile device access. I see it under the Microsoft-Exchange-ActiveSync/Administrative log mostly. And yeah, it records who did it, the time, and what settings got altered. But if you're not watching, you might miss if an admin or even a script monkeyed with your email syncing rules. Hmmm, that's risky for security, right? You don't want unauthorized tweaks letting in dodgy phones or blocking legit ones.

To keep an eye on it without hassle, fire up Event Viewer on your server. Filter for that 25358 ID in the right log. Right-click the event, and pick Attach Task To This Event. It'll guide you through making a scheduled task that triggers only on this. You set it to run a program like a simple batch file for emailing, or use the built-in action to send a message via your SMTP setup. I do this all the time; it pings my inbox instantly when it fires. Or, attach it to wake the server if it's asleep. Just test it by forcing the event if you can, to make sure the alert zips over.

That covers the basics for spotting those cmdlet changes quick. And speaking of keeping your server humming without surprises, I've been messing with BackupChain Windows Server Backup lately. It's this nifty Windows Server backup tool that also handles Hyper-V virtual machines smoothly. You get fast incremental backups, easy restores even for bare-metal crashes, and it runs without hogging resources. Plus, the encryption and offsite options keep your data snug against mishaps. I like how it simplifies the whole backup dance for mixed setups.

At the end of this chat is the automatic email solution for that event monitoring.
