Required Application Roles

Avanan need these roles during onboarding:

• Exchange Administrator

• Privileged Authentication Administrator

Exchange Administrator

Avanan uses the Exchange Administrator role to perform these tasks in several methods including running PowerShell commands.

• Initial onboarding - To configure Mail Flow Rules, Connectors, and additional elements for incoming, internal, and outgoing mail flow, as required to enforce the configured DLP, Threat Detection, and Click-Time Protection policies. For more information, see Automatic Mode Onboarding - Microsoft 365 Footprint.

• Unified Quarantine - Filter information about emails quarantined by Microsoft and, if required, restore them from the Microsoft quarantine.

• Track Microsoft Spam Policy - To determine what Microsoft would have done with every email, Avanan checks for updates in your configured Microsoft policy for every Spam confidence level (SCL).

• Integration with Microsoft Encryption - To enable the integration with Microsoft Encryption to support DLP policy rules with the Email is allowed. Encrypted by Microsoft workflow. For more information, see DLP Policy for Outgoing Emails.

• Automated maintenance - To enhance troubleshooting capabilities and support infrastructure growth.

• To support new features in the future.

Privileged Authentication Administrator

Avanan uses the Privileged Authentication Administrator role to block users and reset their passwords if they are detected as compromised. See Remediating Compromised Accounts.

Reducing the Assigned Microsoft Application Role

• Avanan uses the Privileged Authentication Administrator role to block accounts that are detected as compromised. This role allows to block every compromised account, even if it is a Global Administrator. For more information, see Remediating Compromised Accounts.

• After successfully Activating Office 365 Mail, administrators can reduce the Privileged Authentication Administrator role to any of the roles described in this Microsoft article.

• Once you do that, Avanan will only be able to block compromised accounts that the selected role can reset their password (see this Microsoft article).

  Notes: When reducing the application role, make sure to apply the lesser role first (see this Microsoft article) and then remove the more privileged role (see this Microsoft article). If you have connected Avanan to Office 365 Mail prior to December 09, 2024, your application might be assigned with the Global Administrator role. You can manually reduce this role to Exchange Administrator, Privileged Authentication Administrator or a lesser role.

Microsoft 365 Mail - Approving User

As part of activating Office 365 Mail protection, you need a user with the Privileged Role Administrator role or higher to approve the required permissions for the application.

Use of Azure AD Graph APIs

As part of the integration with Microsoft, Avanan uses some Azure AD Graph APIs.

Since Microsoft is about to deprecate these APIs, you may receive notifications stating that a service principal (Avanan) uses an API scheduled for deprecation.

Avanan is actively migrating the remaining API calls from Azure AD Graph APIs to the newer Microsoft Graph APIs.

Avanan completes the migration before the end of June 2025.

For now, you can disregard these alerts from Microsoft.
