IMAP error codes and Microsoft draft deletion fixes

Email

Fixed

Section titled “Fixed”
  • Internal grant-fetch failures on IMAP-hosted grants now correctly return a 5xx server error instead of 401 Unauthorized. If your integration treated 401 from IMAP requests as an invalid-credentials signal, note that some of those responses were actually internal Nylas errors and should be handled (and retried) accordingly.
  • Deleting a draft on a Microsoft Graph grant now permanently removes it. Previously, a deleted Microsoft draft could remain retrievable.
  • Fetching a deleted Microsoft draft now correctly returns 404 Not Found.
