service principals rotation

Service principals rotation involves regularly updating credentials and secrets for Azure AD or Microsoft Entra ID service principals to reduce the risk of credential compromise. While the tagged content focuses on Exchange Server security, administrators managing hybrid or cloud-connected Exchange environments often rely on service principals for authentication and automation. Best practices include using managed identities where possible, setting expiration policies for client secrets and certificates, and automating rotation with tools like Azure Key Vault or PowerShell scripts. Regular rotation limits the blast radius of leaked credentials and aligns with zero-trust security models. For Windows and Microsoft 365 environments, service principals rotation is a critical operational security task.
