New-ClassificationRuleCollection Exchange cmdlet issued (25551) how to monitor with email alert

[bob]

That event 25551 pops up in your Event Viewer when someone fires off the New-ClassificationRuleCollection cmdlet in Exchange. It flags that a fresh bunch of rules got slapped together for classifying emails or data. You see it under the MSExchange Management log mostly. The details spill out who did it, like the user account, and when exactly it happened. Sometimes it lists the name of the new collection too. I check mine whenever admins tweak email policies. It keeps things from going haywire with sensitive stuff. And yeah, it logs the server name involved. But if it's unauthorized, that could mean trouble sneaking in. You want to watch it close on busy servers.

I always set up alerts for stuff like this so you don't miss a beat. Open Event Viewer first thing. Right-click on the log where it shows up. Pick Attach Task To This Event. You build a scheduled task from there. Make it trigger on event ID 25551. Then hook it to send an email when it fires. I tweak the action to run a program that pings your mail setup. Or just use the built-in send email option if you got it configured. Test it out once to make sure it buzzes your inbox right away. Keeps you in the loop without staring at screens all day.

Hmmm, tying this back to keeping your server safe from odd changes. You might dig BackupChain Windows Server Backup for backups that cover all that. It's a solid Windows Server backup tool. Handles virtual machines with Hyper-V too. I like how it snapshots everything quick without downtime. Restores files or whole VMs in a snap. Saves you headaches from lost configs or attacks. Plus it encrypts data on the fly. Way better than fumbling with built-ins.

At the end here is the automatic email solution.

Note, the PowerShell email alert code was moved to this post.
