List configured personal Microsoft accounts and delegated scopes, without OAuth or credential access. Choose explicit opaque account IDs for subsequent requests.

List/search messages across an intentional account selection using structured sender, subject and date filters. Includes mailbox folders such as Deleted Items. Not Gmail syntax or full-text search. Each account has independent pagination; repeat the identical filters/pageSize with its cursor.

Read one immutable message ID, with bounded inert content and attachment metadata. Does not mark read, fetch images or execute content.

List inert attachment metadata for a message, with account-bound pagination. Does not download attachment content.

Read one page of messages sharing conversationId in this mailbox. No Gmail thread resource is assumed; follow nextCursor with the same account, conversation and pageSize for complete results. No snapshot or cross-mailbox completeness guarantee.

Read a file attachment as bounded inert base64 bytes (up to 2 MiB). Item and reference attachments are rejected; no URL is followed and nothing is executed or written to disk.

Create an UNSENT draft only. Explicit accountId and durable requestId required. Supports Unicode JSON bodies and validated To/Cc/Bcc; HTML is attribute-free formatting only. No send capability exists.

Create an UNSENT reply/reply-all using Graph createReply/createReplyAll. Graph derives Reply-To, recipients and conversation headers from the source; arbitrary recipient/header overrides and sends are unavailable. Source versions are rechecked, not atomically locked.

Discover this explicit account's accessible calendars. Unknown permissions and partial results remain explicit; no calendars are created or shared.

Read a selected accessible calendar and its Graph-reported permissions. default resolves /me/calendar.

Read bounded UTC calendarView occurrences, exceptions and single events. Follows all safe pages up to limits; complete=false is never a complete/free result.

Literal case-insensitive subject/bodyPreview search over an explicitly selected, bounded calendarView. Partial reads produce partial search results.

Read one exact immutable event ID within the selected calendar, preserving master/originalStart and original zones.

Get exact occurrence/exception IDs from a verified seriesMaster in a bounded window. Use returned ID, master and originalStart for occurrence actions; never derive IDs from dates.

Derive free/busy ONLY from explicitly selected accessible account/calendar sources via fully paginated calendarView. Personal getSchedule/findMeetingTimes are not supported. Any partial/failed/unknown source prevents common free time.

Find common UTC slots across every explicit account/calendar source. Busy, tentative, OOF, working-elsewhere and all-day events block; unknown or incomplete data yields no slots.

Create an appointment or invitation with explicit Windows-zone local times and bounded Graph recurrence. Invitations require human WebAuthn review. Private guest-free creates are exempt only with provider-proven own/private calendar evidence; missing sharing evidence means review. No online meeting creation.

Patch ONLY supplied fields on an organizer event. ALL updates require human WebAuthn review. Explicit seriesMaster or verified exact occurrence targeting; no this-and-following. Online meeting body editing is rejected. Resource re-read is not atomic concurrency control.

Delete only the explicitly reviewed single event, whole seriesMaster or verified exact occurrence. Human WebAuthn review is always required; organizer deletion sends attendee cancellations.

Respond only as the actual authenticated attendee of a default-calendar invitation. Requires explicit sendResponse=true and human WebAuthn review; no attendee identity override. Declining may remove the event; Graph actions have residual external-edit races.

Read the status of an explicitly selected account's write. An unknown outcome must never be blindly retried.

Cancel a pending operation before dispatch. Does not undo an already-dispatched Outlook action.
