Azure AD Access Review

Hi,

We are planning governance around Guest Access to Office 365 SharePoint and One Drive. We are exploring various options that will help us govern Guest Access and clean up the access on regular basis.

• Does Azure AD Access Review does good job in generating necessary reports and cleaning up the guest accounts?
• Does Azure AD Access review send out notification to admins to disable / remove stale guest accounts?
• Are there any third party tools that can do better job than Azure AD access review with more in depth reporting and governing the guest access?

Thanks.
