Summary

AI summary

Outlook tokens no longer expire and require manual re-authentication due to automatic refresh.

Full changelog

Fixes

  • Outlook automatic token renewal — tokens no longer expire and require manual re-authentication. Uses MSAL file-based cache persistence with acquireTokenSilent() for reliable automatic refresh.
  • IMAP search errors now surface actual server diagnostics instead of opaque "Command failed"

Changes

  • Outlook auth persists MSAL token cache to ~/.email-mcp/msal-cache.json
  • refreshTokenIfNeeded() now logs refresh failures instead of silently swallowing them
  • Added msal_home_account_id field for MSAL account identification
