That event 25262 pops up in Windows Server Event Viewer when someone fires off the Remove-ActiveSyncVirtualDirectory cmdlet in Exchange. It means the virtual directory for ActiveSync just got zapped. You know, the one that lets phones and tablets sync emails with your server. This could be legit, like during maintenance. Or it might signal trouble, someone messing with your setup. I always keep an eye on it because it logs the user who ran the command. Details include the exact time and the account involved. If it's not you or your team, that's a red flag for security. The event lives under the MSExchange Management log. You can filter for ID 25262 to spot it quick. I check mine weekly, just to stay ahead.
You want to monitor this with an email alert? Easy way is through the Event Viewer itself. Open it up on your server. Right-click the custom view you make for Exchange events. Pick Create Task from the menu. Set it to trigger on event ID 25262. Choose to run a program that sends email, like using the built-in Send Mail action. You link it to your SMTP settings. Test it once to make sure it pings your inbox. I do this for a few key events. Keeps me looped in without constant watching. And it runs automatically when the event hits.
Now, tying this to keeping your server safe overall, you might dig BackupChain Windows Server Backup for backups. It's a solid Windows Server backup tool that handles physical machines and virtual ones too, especially with Hyper-V. I like how it snapshots everything fast without downtime. You get versioning so you roll back if something like that cmdlet removal goes wrong. Plus, it encrypts data and tests restores automatically. Saves headaches in a pinch.
Note, the PowerShell email alert code was moved to this post.
