Gemini agent vs Agent 365: the agent identity decision
Google introduced the Gemini agent on 8 October 2026: a universal work agent whose coworker agents get their own @agents.company.com mailbox, calendar and Drive, in private preview with no price. We set it against Microsoft Entra Agent ID and Agent 365, both GA since spring at $15 per user per month, compare the two identity models, run the cost math for a 1,000-user Swedish M365 shop, and list the EU residency and offboarding questions to ask before a pilot.
OpenAI Dots and the audit log: whose action was that?
A standard OpenAI dot acts on its owner's account, so downstream logs name the employee and cannot separate attended from unattended action, while Microsoft's Entra agent labels never see it. Specialist dots with their own identity are in pilots with an undated Agent 365 integration, so today's controls are plugin scope, the four rule levels, role permissions and a usage policy written for agents.
