Same delegated shape as the Microsoft 365 provider, through the same
broker interface: the admin registers an OAuth client in Google Cloud
Console, connects the Google account the installation should send as,
and outgoing email goes through the Gmail API's messages.send as that
account.
The shared authorization-code machinery (exchange, refresh, token
storage, id_token account detection, RFC 6749 failure telling a dead
grant from a transient one) moves into an abstract OAuthCodeFlowBroker;
the two vendor brokers keep only their endpoints, scopes and consent
URL parameters. Google's quirks live where they belong: offline access
with a forced consent screen (the only way Google issues a refresh
token), and a refresh response that never re-sends one — the store
keeps what it has.
The settings screen needed no changes: the dropdown, the credential
form and the connect flow all derive from the provider enum.
Adds "Microsoft 365 (OAuth)" to the Email settings provider dropdown.
Selecting it swaps the SMTP form for an app registration (client id,
secret, optional tenant) and a "Connect mailbox" flow: the admin signs
into the mailbox the installation should send as, and outgoing email
goes through Graph sendMail as that mailbox — no password, no app
password, no SMTP AUTH, which Microsoft is winding down.
Delegated flow on purpose: it needs no admin consent and works for
work/school and personal accounts alike. Its one weakness — a grant
can die silently behind a password reset or a Conditional Access
change — is answered by a daily scheduled refresh that keeps the
token alive and, on a dead grant, warns the settings admins once
in-app and on the settings page instead of letting mail stop quietly.
Tokens and the client secret live encrypted in their own row and are
read fresh at send time, never through the boot-config cache. The
stored SMTP transport survives a provider switch untouched.
Client file sharing, rebuilt from the ground up: a private area per
client, resumable uploads, folders, groups and categories, sharing with
expiry dates and download limits, comments, file versions, an activity
log, a REST API, and sixteen languages.
