Microsoft Purview Finally Logs Portal Access Checks, Because Apparently That Was Too Much to Ask Before

Microsoft has shoved a mildly useful update into Purview: it now records audit events for portal access checks. Yes, really. In the year of our cursed infrastructure, they’ve finally decided admins might want to know when someone checks whether they can get into a portal. Bloody revolutionary.

The article explains that Microsoft Purview’s audit logging now includes events tied to access checks for Microsoft 365 portals and admin centers. So when a user or admin hits a portal and the system evaluates whether they’re allowed in, that check can now show up in the audit trail. Which is the sort of thing any sane admin would’ve expected from the start, but here we are, clapping because the vendor found the “log it” checkbox.

Why does this matter? Because when users whine that they “couldn’t access” something, or security wants to know whether someone probed a portal they weren’t entitled to use, you now have some actual bloody evidence instead of the usual pile of guesswork, stale coffee, and prayer. It gives admins and compliance people a clearer picture of who tried to access what, when the check happened, and whether the system had a look before telling them to piss off.

The piece points out this is useful for investigations, troubleshooting, and compliance work. In other words: when management inevitably asks why Bob from Accounts was sniffing around an admin portal, you may now have logs showing the access evaluation took place. Not a full miracle, mind you, but at least a breadcrumb trail instead of the usual smoking crater.

There are, naturally, caveats. These events are part of the ever-expanding swamp of Purview audit data, so admins still need to know where to look, what licenses they’ve been conned into buying, and how to interpret the damn things. Logging existing is not the same as logging being easy to query, easy to retain, or easy to explain to some security committee stuffed with buzzwords and no clue.

The key takeaway: Purview now captures portal access check events, which means better visibility into attempted portal access and a slightly less miserable time for admins doing audits, investigations, or post-incident archaeology. It’s useful, overdue, and the sort of feature that makes you mutter, “about fucking time,” before getting dragged into another meeting that should’ve been an email.

Anecdote time: years ago, a manager demanded to know who “tried to break into” an admin console. We had no logs for the access check, of course, because that would’ve been sensible. So we spent six hours digging through unrelated telemetry while the manager hovered like a gull over chips. Turned out it was his own assistant clicking the wrong bookmark. If we’d had this sort of audit event back then, I could’ve saved the day in two minutes and spent the other five hours and fifty-eight telling everyone else to fuck off.
