b2 of the multi-provider email roadmap. Mirrors the Gmail provider's shape
end-to-end so the two stay structurally interchangeable:
- MicrosoftGraphConnection model + table (reconciler pattern, SQLite+MySQL,
same shape as GmailConnection: encrypted refresh/access token, sync state).
- MicrosoftGraphOAuthService: auth-code + offline-access flow against
login.microsoftonline.com, encrypted token storage via IDataProtector,
message search/thread/detail fetch against Microsoft Graph (conversationId
stands in for Gmail's threadId), attachment listing.
- MicrosoftGraphProvider implements IEmailProvider — no contract changes;
the existing seam was already provider-neutral.
- MicrosoftGraphController: connect-url/oauth/callback/status/disconnect,
mirrors GmailController's OAuth surface exactly (including the popup
postMessage handshake). Job-matching/review endpoints stay Gmail-only for
now, per the roadmap — generalising those needs the frontend provider
picker work, not this slice.
- Registered in DI + IEmailProviderRegistry (multi-registration of
IEmailProvider, resolved by ProviderKey).
- Config: Microsoft:ClientId/ClientSecret/TenantId/RedirectUri, wired through
docker-compose.yml + .env.example alongside the existing Google:Gmail* keys.
- Tests: MicrosoftGraphControllerTests (OAuth lifecycle) +
MicrosoftGraphProviderTests (DTO mapping onto the neutral contract).
147/147 green (135 existing + 12 new).
