To configure Job Queues in Business Central to run under a "system user" without relying on a constantly monitored Office 365 email or complex workarounds:
The most efficient and standard method is to create a dedicated, non-interactive Azure AD user (e.g., svc.bc.jobs@yourdomain.com). This user should be assigned a Business Central license and the necessary permission sets. You then assign this user's ID to the User ID field for each Job Queue entry. This provides a secure, auditable, and stable context for job execution without needing a "real admin" email for authentication or complex instance setups.
