Permissions required for Active Directory and Microsoft 365 accounts used by Cayosoft Administrator

Summary: Cayosoft recommends using a service account with Domain Admins rights for Active Directory and Exchange management, and an account with the Global Admin role for Microsoft 365 management. Global Admin role assignment is not a hard requirement, but it does make it easier to configure Cayosoft Administrator. If you need to restrict Cayosoft service accounts' rights, this article contains the minimum set of roles and permissions to delegate.

Applies to: Cayosoft Administrator 5.4 or later.

Permissions required for Microsoft 365 Management

General requirements 

The Microsoft 365 connection account is the account that is used in Microsoft 365 Extension with Microsoft 365 credentials specified. Microsoft 365 connection account must always meet the following criteria:

1. The connection account must have a Global Administrator role assigned.
2. The connection account must be excluded from the Conditional Access Policy (CAP) and from Multi-factor Authentication (MFA). 
3. The connection account must be granted Administrative Consent to access your tenant. The list of permissions is here: Azure AD application permissions required by Cayosoft Administrator Service.  
4. The connection account must have an Organization management role, whether through the Global Admins role, through Exchange administrators, or directly in Exchange Online through direct membership in a role.
5. The connection account must be a cloud-only account to avoid issues with Azure AD synchronization and should not be used in other services or scripts.

6. The connection account should have the corresponding Microsoft 365 licenses assigned for specific functionality like Teams management, and if you use the same account in Email settings, for email notifications.

7. Additional roles in Exchange Online should be assigned for Priority booking web action.

Configuring granular permissions for Microsoft 365 connection account

This is a step-by-step instruction on how to configure Cayosoft Administrator Service to manage Microsoft 365 under the account without the Global Administrator role:

1. In Microsoft 365 extension specify credentials for Microsoft 365 account. You can create a new connection account that will be added to Azure AD roles and granted consent automatically or use an existing account that you will need to configure manually. 
2. Delegate the Global Administrator role to the account. Role assignments will be changed to a customized administrator later.
3. Grant consent as it is described in this KB article: How to grant admin consent to Azure APIs and connect to the Microsoft Graph API. Login to Microsoft 365 under the same account that is defined on Microsoft 365 extension.
4. Change roles that are assigned to Cayosoft account in Microsoft 365 Admin Portal (https://admin.microsoft.com):
   1. Change role to Customized Administrator
   2. Select roles: 
      Note: You can find the detailed description of each Microsoft 365 role in the Microsoft documentation: About MS 365 admin roles.
      
      • Exchange Administrator
      • License Administrator
      • User Administrator
      • Global Reader

      • Privileged Authentication Administrator

        Note: Assign this role if you want to use Cayosoft Administrator to manage legacy MFA settings for Global Administrators or authentication methods for users.
      • Teams Administrator 
        Note: Assign this role if you plan to manage Microsoft Teams.
