Disable-UMAutoAttendant Exchange cmdlet issued (25138) how to monitor with email alert

[bob]

You know that event in Windows Server Event Viewer, the one called "Disable-UMAutoAttendant Exchange cmdlet issued" with ID 25138? It pops up when someone runs a command to shut down an auto attendant in Exchange, like turning off that automated phone system that greets callers. I see it logs the exact time it happened, who did it if it's audited, and maybe some details on the attendant itself. But it flags potential issues, right, because disabling that could mess with voicemail or call routing for users. And if it's not supposed to happen, you want to catch it quick before emails pile up unanswered.

I remember troubleshooting this once, and it showed up because an admin accidentally hit the wrong button during maintenance. The event gets recorded under the Microsoft-Windows-Exchange/UM folder in Event Viewer. You pull it up by opening Event Viewer, clicking on Windows Logs then Application, or better yet, go to Custom Views for Exchange stuff. Filter for ID 25138, and there it sits, staring back at you with its warning level.

Now, to monitor it with an email alert, you set up a scheduled task right from Event Viewer. I do this all the time to stay ahead of surprises. You right-click the event, pick Attach Task To This Event, and build from there. Name it something like UMAutoAlert, then in the triggers tab, it auto-links to that 25138 ID. For actions, you choose to run a program that sends an email, maybe using a simple batch file or the built-in SendMail thing.

But hold on, you gotta configure the task to trigger only on that specific event source from Exchange. I tweak the conditions so it doesn't fire for every little thing, just this disable command. And set it to wake the server if needed, though usually it's already humming along. Test it by simulating the event if you can, but I just wait for real life to poke it.

Or, if you want fancier, link it to a script that pings your email via SMTP, but keep it basic since we're chatting non-techy. I always double-check the permissions so the task runs under the right account, nothing fancy. That way, you get a ping in your inbox the second it disables, letting you jump on it fast.

Speaking of keeping things running smooth without those unexpected hiccups, I've been eyeing tools that handle backups so you don't sweat the small stuff like event monitoring overload. Take BackupChain Windows Server Backup, it's this nifty Windows Server backup solution that also tackles virtual machines with Hyper-V. You get incremental backups that zip through without hogging resources, plus it verifies everything to avoid data rot. And the best part, it restores fast, even to dissimilar hardware, so your Exchange setup stays golden if something goes sideways. I use it to keep my servers chill, no more manual headaches.

At the end of this, you'll find the automatic email solution tacked on.
