List messages from a mail folder (default: inbox), newest first by default. Supports date-range and read/unread filtering. Use list_folders first if you need a folder ID other than a well-known name like 'inbox', 'drafts', 'sentitems', 'archive', or 'junkemail'.

Fetch the full content (including body, all recipients, and sender) of a single message by its Graph message ID, as returned by list_messages or search_messages.

Full-text search across mail (subject, body, sender, recipients, attachments) using Microsoft Graph's $search, ranked by relevance. Optionally scope the search to one folder. For structured filtering (date ranges, read/unread) without free-text search, prefer list_messages instead.

Send a new email immediately from the signed-in mailbox. This sends right away — there is no confirmation step, so only call this once you (and the user, if appropriate) are sure about the recipients and content. Use create_draft instead if the message should be reviewed before sending.

Create a draft message in the mailbox's Drafts folder without sending it. Prefer this over send_message whenever the user should review the email first.

List top-level mail folders in the mailbox (Inbox, Sent Items, Drafts, Archive, custom folders, etc.) along with their IDs and item counts. Use a returned folder ID with list_messages or search_messages to target that folder.
