Audit logs in Azure Active Directory

As an IT administrator, you want to know how your IT environment is doing. The information about your system’s health enables you to assess whether and how you need to respond to potential issues.

To support you with this goal, the Azure Active Directory portal gives you access to three activity logs:

  • Sign-ins – Information about sign-ins and how your resources are used by your users.
  • Audit – Information about changes applied to your tenant such as users and group management or updates applied to your tenant’s resources.
  • Provisioning – Activities performed by the provisioning service, such as the creation of a group in ServiceNow or a user imported from Workday.

This article gives you an overview of the audit logs.

What is it?

With the audit logs in Azure AD, you get access to records of system activities for compliance. The most common views of this log are based on the following categories:

  • User management

  • Group management

  • Application management

With a user-centric view, you can get answers to questions such as:

  • What types of updates have been applied to users?

  • How many users were changed?

  • How many passwords were changed?

  • What has an administrator done in a directory?

With a group-centric view, you can get answers to questions such as:

  • What are the groups that have been added?

  • Are there groups with membership changes?

  • Have the owners of group been changed?

  • What licenses have been assigned to a group or a user?

With an application-centric view, you can get answers to questions such as:

  • What applications have been added or updated?

  • What applications have been removed?

  • Has a service principal for an application changed?

  • Have the names of applications been changed?

  • Who gave consent to an application?

What license do I need?

The audit activity report is available in all editions of Azure AD.

Who can access it?

To access the audit logs, you need to be in one of the following roles:

  • Security Administrator
  • Security Reader
  • Report Reader
  • Global Reader
  • Global Administrator

Where can I find it?

The Azure portal provides you with several options to access the log. For example, on the Azure Active Directory menu, you can open the log in the Monitoring section.

What is the default view?

An audit log has a default list view that shows:

  • the date and time of the occurrence
  • the service that logged the occurrence
  • the category and name of the activity (what)
  • the status of the activity (success or failure)
  • the target
  • the initiator / actor (who) of an activity

Microsoft 365 activity logs

You can view Microsoft 365 activity logs from the Microsoft 365 admin center. Even though Microsoft 365 activity and Azure AD activity logs share a lot of the directory resources, only the Microsoft 365 admin center provides a full view of the Microsoft 365 activity logs.

You can also access the Microsoft 365 activity logs programmatically by using the Office 365 Management APIs.


Most standalone or bundled Microsoft 365 subscriptions have back-end dependencies on some subsystems within the Microsoft 365 datacenter boundary. The dependencies require some information write-back to keep directories in sync and essentially to help enable hassle-free onboarding in a subscription opt-in for Exchange Online. For these write-backs, audit log entries show actions taken by “Microsoft Substrate Management”. These audit log entries refer to create/update/delete operations executed by Exchange Online to Azure AD. The entries are informational and don't require any action.
