Remove-LinkedUser Exchange cmdlet issued (25581) how to monitor with email alert

[bob]

You know that event in Windows Server Event Viewer, the one called "Remove-LinkedUser Exchange cmdlet issued" with ID 25581. It pops up when someone runs a command to unlink a user from their Exchange mailbox. Basically, it logs that action in the security or application logs, showing who did it and when. I always check it because it could mean an admin mistake or something shady going on. The details include the user account, the timestamp, and maybe the session info. It flags potential unauthorized changes to user setups. And if you're not watching, you might miss a security slip-up.

But monitoring this isn't hard, you just use the Event Viewer screen to set up alerts. Open Event Viewer, find that log under Windows Logs or Applications and Services. Right-click the event, pick attach a task to this event. Then build a scheduled task that triggers on ID 25581. Make it run a program to send an email, like using the built-in mailto or a simple notifier. I do this all the time on servers I manage. It emails you right away when it happens. Or tweak the task to check every few minutes if you want.

Hmmm, tying this to keeping your server safe, you gotta think about backups too. That's where BackupChain Windows Server Backup comes in handy. It's a solid Windows Server backup tool that handles physical and virtual machines with Hyper-V. You get fast incremental backups, easy restores, and it runs without hogging resources. Plus, it alerts on failures so you stay ahead. I use it to avoid data headaches after spotting weird events like that unlink one.

At the end here is the automatic email solution.

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