Stop guessing who has access to what. YouAttest connects directly to your Microsoft 365 environment so you can see exactly who can reach your files — and cut that access the moment a review says they shouldn’t.
Youattest for Microsoft 365

What Is a Microsoft 365 Access Audit?

A Microsoft 365 access audit is a regular check of who can reach your files in SharePoint, Teams and OneDrive, and whether they still should. YouAttest audits access at the site, library and file-sharing level, sends reviewers a campaign to certify or revoke each user, and exports PDF or CSV evidence for your auditors.

How YouAttest Connects to Microsoft 365

YouAttest connects to Microsoft Entra ID with SAML single sign-on, typically in about 15 minutes. SharePoint audits (sites, libraries and file sharing) add a one-time setup: an admin creates a certificate, uploads it to an app registration in your Entra tenant, and enters the thumbprint and SharePoint domain in YouAttest. SharePoint audits are available for Microsoft Entra ID tenants, for admin accounts with the SharePoint feature enabled.

The Challenge

Why This Is Harder Than It Looks

Most organizations don’t have a clear picture of who can access what inside Microsoft 365. By the time compliance asks for an access report, the data is a mess. YouAttest pulls that picture together — with the ability to revoke access directly from the same screen.

Files shared in a hurry

Permissions get granted in the moment and never revisited.

Lingering guest accounts

Guests stick around long after their projects have ended.

Live anonymous links

Links created months ago are still open with no expiry.

Messy compliance data

Access reports arrive scattered and impossible to trust.

Full Coverage

Where YouAttest Connects in M365

One review workflow across your entire Microsoft 365 stack — nothing slips through the cracks.

Entra ID

Where YouAttest starts. It reads your directory data to confirm every user with file access is still an active employee, contractor, or approved guest — not a ghost account.

SharePoint

Target individual sites or run a broad campaign across your entire environment. Library-level and file-level permissions are both fully covered.

Teams

Files shared in Teams channels don't always follow SharePoint's rules. YouAttest audits those too, so nothing slips through in a busy workspace.

OneDrive

Personal business links from OneDrive are easy to forget and hard to track manually. YouAttest brings them into the same review workflow as everything else.

Sharepoint

SharePoint Library Audits

When you run a Library Access audit, YouAttest works through your SharePoint environment at three levels — no opening folders, no spreadsheets.

Site-level reviews

See who has access at the library root across every site, all at once.

File-level overrides

Find files where permissions were manually changed so they no longer inherit — usually the riskiest ones.

External & anonymous links

Flag any links that allow outside access — especially those with no expiration date set.

Sharing Risk

File Sharing Audits

Shared links are a slow-burn risk. Someone shares a file for a vendor review, the project ends, and the link sits there indefinitely. YouAttest finds them.

Time-based filtering

See which links have no expiration or have already blown past your policy limit.

Sharing type breakdown

Internal, external, and anonymous access are separated out so reviewers can prioritize.

The Workflow

How It Works: Audit to Revocation

Admin accounts with M365 / SharePoint integration enabled can create and execute audits — the full lifecycle, from campaign creation to access removal.

Create Audit

Name it, connect your API source, set target sites & a due date.

Assign Reviewers

Reviewers certify or revoke each item from a single screen.

Mark Complete

Campaign locks; the Execute action unlocks automatically.

Execute

Admin confirms revocation after a required confirmation step.

Access Governance for SharePoint, Teams and OneDrive

The Problem With M365 Permissions Over Time

Microsoft 365 is built for speed. People share files fast, spin up new Teams channels, and grant guest access without a second thought. That’s fine in the moment. The problem is what happens six months later when none of that has been reviewed.
Platform What YouAttest Does
SharePoint sprawl
Repositories keep growing. Without regular reviews, no one knows who still needs what.
Teams over-sharing
Channels pile up with permissions that were set once and never revisited.
OneDrive link leakage
Personal shared links bypass the controls that apply to shared drives.
Entra ID misalignment
Permissions stick around long after someone leaves a team, a project, or the company.
One Workflow

How YouAttest Covers the Full M365 Stack

Platform What YouAttest Does
Microsoft Entra ID
Reads from your directory first, so every audit reflects who’s actually active — not who was active when the permissions were first set.
SharePoint
Site access, library access, and file sharing are all covered. Scope an audit to one site or run it across your entire tenant.
Teams
Files attached to Teams channels get audited alongside everything else. Old collaboration data doesn’t stay visible to people who no longer need it.
OneDrive
Employee cloud drives are included in the same review workflow. No separate process, no gaps.
Getting Started

Setting Up an Audit: Step by Step

Admin accounts with SharePoint integration enabled can create and execute audits in four quick steps.

Open the audit section

SharePoint Audit → File Sharing Audits → Create Audit.

Select SharePoint

Choose SharePoint as your audit type from the configuration screen.

Name & connect

Name the campaign, connect your API source, and set a compliance due date.

Choose & done

Pick the specific sites or file paths you want reviewed, then click Done.

Enforcement

What Happens After the Review

Once your reviewers finish, enforcing the decisions takes one click — with a safeguard before anything is removed.
Execute unlocks automatically

It only appears once the audit is marked complete — no accidental early action.

Revocation is comprehensive

Internal users, external vendors, anonymous links — all cut in the same operation.

There's a confirmation step

You'll see a dialog before removal, so no one makes an irreversible mistake under pressure.

Microsoft 365 Access Audit FAQ

What does YouAttest audit in Microsoft 365?

Entra ID users, SharePoint sites and libraries, file sharing (internal, external and anonymous links), and the files in Teams and OneDrive. Reviewers see who has access and can certify or revoke it from one screen.

How does YouAttest connect to Microsoft 365?

YouAttest connects to Entra ID with SAML single sign-on. SharePoint audits add a one-time setup in which an admin uploads a certificate to an app registration in your Entra tenant and enters the thumbprint and SharePoint domain in YouAttest. The YouAttest SharePoint user guide covers each step.

Which Microsoft tenants does it work with?

SharePoint audits are available for Microsoft Entra (Azure) tenants, for admin accounts with the SharePoint feature enabled.

How does revocation work?

Once reviewers finish, an admin marks the audit complete and the Execute action unlocks. A confirmation dialog appears before anything is removed, and access is then revoked for every flagged user, whether the access was internal, external or through an anonymous link.

How is YouAttest different from Entra ID access reviews alone?

Entra ID reviews center on group membership and roles. YouAttest audits at the site, library and file-sharing level, delegates reviews to the people who own the content, and produces consolidated reports that link users, permissions, review decisions and attestations. It extends Entra ID rather than replacing it.

Can YouAttest find old or anonymous sharing links?

Yes. File sharing audits show which files are shared internally, externally or through anonymous links, whether each link has an expiration date, and whether that date runs past your policy. You can audit the whole tenant or specific users and export the results to CSV.

What can reviewers do?

For each user, reviewers can certify, revoke or delegate access. Admins can auto-delegate reviews to managers, mark the audit complete, and download PDF or CSV reports.

Can we review apps outside Microsoft 365 in the same campaign?

Yes. Upload a CSV of entitlements from other apps and review them alongside your Microsoft 365 users. YouAttest's AI-based Identity Trust Score™ and change triggers are available too.
