Authentication

• Type: OAuth against Microsoft Graph (per-user).
• Scopes: User.Read, Mail.ReadWrite, Mail.Send, Contacts.Read.

Access control mapping

• Per-user mailbox; each connected user is the sole owner of their messages and attachments in the graph.

Sync cadence

• Default cron: every 15 minutes.
• Incremental sync: Microsoft Graph delta links per folder, plus next-page links for pagination during the initial backfill. Contacts have their own sync token.

Notable

• Implements IEmailTask — Outlook mail can be the workspace's outbound mailer for the connected user.
• Handles MailboxIsInactiveOrOnPremisesException cleanly when a user's mailbox is on-prem or disabled.
