What are "Connected Apps" in Microsoft 365?
These are non-Microsoft apps that have been granted access to your Microsoft 365 tenant — often through familiar Microsoft consent screens.
“Sign in with Microsoft” often grants apps ongoing access — not just login.
Practical Guidance
Vendor-neutral checklists IT teams use to review OAuth and webhook access.
Why Connected Apps Accumulate in
Microsoft 365
One app. Too much access.
Real business risk.
Microsoft 365 is designed to integrate with SaaS tools, vendors, and internal applications. Over time, apps are added for CRM, e-signature, scheduling, helpdesk, reporting, and automation — and most are never revisited.

How OAuth App Access Creates Hidden Tenant Risk
One app. Too much access.
Real business risk.
“Sign in with Microsoft” isn’t just login — it can grant connected apps access to mail, files, calendars, and user data. That access may be granted by users or administrators, can apply tenant-wide, and does not automatically expire when people leave or projects end.

-
OAuth access can persist without reauthentication
-
Permissions granted early often remain unchanged
-
App activity is less visible than user sign-ins
-
Ownership and approval history can become unclear
01
What do you see?
-
Dozens of connected apps
-
Apps with broad or persistent permissions
-
Apps added years ago and never revisited
-
Apps with no clearly assigned owner
When teams review connected apps for the first time,
the findings are rarely “nothing.”
02
What is unclear?
-
Who owns which apps today?
-
What level of access each app still needs?
-
Whether access was approved intentionally or inherited?
03
Where do teams get stuck?
-
Unsure where to start reviewing
-
No consistent way to assess risk
-
No clear process for documenting decisions
What IT Teams Commonly Encounter
Most of this is normal operational drift — not malicious behavior.
How Connected App Governance Works
One app. Too much access. Real business risk.
