name: Microsoft Exchange Online Mail
version: 1.0.0
description: "Send email from an Exchange Online mailbox through Microsoft Graph — plain-text and HTML bodies (inline data-URI images embedded), attachments of any size, CC/BCC, Reply-To and importance; reply, reply-all and forward an existing message. App-only OAuth 2.0 (tenant ID, client ID, client secret); stdlib-only, no extra Python dependencies."
changelog: "1.0.0 — Initial release: send-mail (text/HTML, inline images, attachments, CC/BCC/Reply-To, importance), reply-mail, forward-mail and a connection test that reads the permissions granted to the app."
category: email

# Per-instance configuration. App-only (client-credentials) OAuth 2.0 against
# Microsoft Graph. The app registration needs the Graph *application*
# permission Mail.Send, with admin consent. Mail.Send lets the app send as any
# mailbox of the tenant: restrict it to the sending mailbox(es) with an Exchange
# application access policy (New-ApplicationAccessPolicy -AccessRight
# RestrictAccess) or RBAC for Applications.
# Two optional permissions widen what the commands accept:
#   - Mail.ReadWrite: attachments over 3 MB in total (draft + upload session).
#   - Mail.ReadBasic.All: reply/forward found by internet_message_id instead of
#     the Graph message id.
