Authenticate a Microsoft account (M365 work/school or personal e.g. Hotmail). Returns the consent URL IMMEDIATELY (does not block): give it to the user, they approve in the browser as the right Microsoft account, and the token saves in the background. Confirm afterwards with microsoft_status. A browser tab also opens automatically as a convenience, but the URL in the response is authoritative if it opens with the wrong profile.

Check connection health for all configured Microsoft accounts with a LIVE credential check against Microsoft (not just local file state). tokenStatus 'needs_reauth' means run microsoft_auth for that account.

Search Outlook messages. Uses KQL syntax (e.g. 'from:name subject:topic', or plain keywords).

Read a specific Outlook message by ID. Returns full message content as plain text.

Create a draft email. Does NOT send — the draft appears in Outlook's Drafts folder for manual review and sending. (The server's Microsoft permissions exclude sending entirely.)

List Outlook mail folders for an account.

List Outlook categories (the Gmail-labels equivalent) for an account.

Create a new Outlook category (the Gmail-labels equivalent).

Apply a category to one or more Outlook messages (by category NAME, not ID).

Remove a category from one or more Outlook messages (by category NAME).

Create an Outlook inbox rule (the Gmail-filter equivalent). Matches incoming messages by criteria and applies actions automatically. At least one criterion and one action required.

Soft-delete: move messages to a 'To Be Deleted' folder. Does NOT delete or trash messages. NOTE: moved messages get NEW message IDs.

List upcoming calendar events. Times are returned in UTC.

Search calendar events by keyword in the title. Times are returned in UTC.

Get full details of a specific calendar event.

Create a calendar event. By default attendees are NOT invited (their names go into the description instead); set send_invites=true to actually invite them — Outlook sends invitation emails to every attendee on the event.

Modify an existing calendar event. CAUTION: if the event has invited attendees, Outlook notifies them of changes automatically.

Soft-delete: prepend 'DELETE - ' to event title. Does NOT actually delete the event.

Check free/busy status for a date or date range (derived from events not marked 'free').

Search Outlook contacts by name, email, or phone number.

List Outlook contacts, optionally filtered by organization or name.
