CAPABILITY PROFILE
What the Outlook integration exposes
The Outlook Agent App exposes 11 provider-backed actions for communication and productivity work. Its current contract lets an authorized agent get the current outlook mailbox settings, including automatic replies, locale, time zone, and working hours, create a new outlook draft message with subject, body, recipients, and other writable message properties, and get a single outlook message by message id, including message metadata and optional body formatting. These operations are called through Working Machines as typed capabilities rather than through browser navigation or copied UI steps.
A connection uses OAuth 2.0. Before execution, the agent can inspect the selected action, its required fields, declared scopes, and expected output contract. Provider credentials remain inside the Working Machines runtime; the calling agent receives the capability and its structured result, not the underlying secret.
For reliable operation, start with the narrowest action that satisfies the task, resolve stable provider identifiers before changing state, and validate the returned object or status after execution. Availability still depends on the connected Outlook account, granted provider permissions, workspace policy, region, plan, and upstream API behavior.

PROVIDER-SPECIFIC WORKFLOWS
Jobs this Agent App can support
Inspect Get Mailbox Settings
Get the current Outlook mailbox settings, including automatic replies, locale, time zone, and working hours. Use this as a bounded discovery step, retain the returned identifier, and avoid expanding the read beyond the task's stated scope.
get_mailbox_settingsControl Create Draft
Create a new Outlook draft message with subject, body, recipients, and other writable message properties. Resolve the target first, present material changes for confirmation, and make retries idempotent where the provider supports it.
create_draftVerify with Get Message
Get a single Outlook message by message ID, including message metadata and optional body formatting. Compare the returned provider state with the intended outcome and preserve stable IDs or canonical links in the run record.
get_messageSAFETY BOUNDARY
Operate Outlook with explicit limits
- Authorize Outlook with OAuth 2.0 and grant only the provider access required by the selected actions.
- 6 actions are change-capable by name. Confirm the target identity and material parameters before allowing a write.
- Do not infer permission from catalog visibility. Workspace policy, connection identity, and upstream authorization still govern execution.
- The sampled contract declares provider scopes including `Mail.ReadWrite`, `MailboxSettings.ReadWrite`, `User.Read`, and `Mail.Send`; verify the complete action contract before execution.
- After a call, inspect the structured result and execution record before reporting that the Outlook task completed successfully.
CONNECTION MODEL
OAuth 2.0
Outlook uses OAuth 2.0. Connection requirements and availability are determined by the provider and the Working Machines deployment.
Working Machines stores provider credentials behind the execution boundary. An agent can use an authorized connection identity, but catalog discovery alone does not reveal OAuth tokens, API keys, or provider secrets.
