Set-AuthRedirect Exchange cmdlet issued (25718) how to monitor with email alert

[bob]

That event, the one with ID 25718, pops up in Event Viewer when someone runs the Set-AuthRedirect cmdlet in Exchange. It means they're tweaking how authentication gets redirected, like pointing login paths to a new spot for security or setup reasons. You see it logged under the MSExchange ADAccess group, and it's usually informational, not an error that breaks things. But if it fires off unexpectedly, could signal someone messing with your server configs without you knowing. I check mine every so often because it tracks admin actions on auth flows. And yeah, it includes details like who issued it, when, and what parameters they used, so you can trace back if needed. Hmmm, sometimes it ties into bigger changes, like updating URLs for Outlook Web Access or mobile logins.

You want to monitor this for email alerts? Easy way without scripts. Fire up Event Viewer on your server. Go to the Applications and Services Logs, then Microsoft, Exchange, Admin Audit or wherever that 25718 hides. Right-click the log, pick Attach Task To This Log. Name it something like AuthRedirect Watcher. Set it to trigger on event ID 25718 exactly. For the action, choose Send an email, but wait, newer Windows skips that built-in, so instead, make it start a program that calls your email setup, or link to a scheduled task that runs on trigger. I do it by creating the task first in Task Scheduler, pointing to a simple batch that emails you via Outlook or whatever you got. Then attach that task to the event in Viewer. Test it by simulating the event if you can, just to see the alert ping your inbox quick. Or, if you're lazy like me sometimes, filter the log view to show only 25718 and check daily till you automate.

Speaking of keeping things smooth and backed up, you might dig BackupChain Windows Server Backup too. It's this solid Windows Server backup tool that handles file-level stuff and even snapshots for Hyper-V VMs without downtime hassles. I like how it encrypts everything on the fly and lets you mount backups like drives for fast recovery. Plus, it scales easy for multiple servers, saving you headaches on restores. And at the end of this, there's the automatic email solution for that monitoring.
