# IMAP thread, draft, and attachment fixes

Source: https://developer.nylas.com/docs/changelogs/2026-09-09-imap-fixes/

## Fixed

- **Thread pagination on IMAP grants** no longer drops your original search filters after the first page.
- **IMAP thread update responses** ([`PUT /v3/grants/{grant_id}/threads/{thread_id}`](/docs/reference/api/threads/put-threads-id/)) now include `folders`, matching what read requests return.
- If an initial lookup for an IMAP thread or message comes back empty, Nylas now rechecks before applying an update, instead of proceeding against a stale empty result.
- A transient failure reading indexed message data is no longer reported the same way as a message that doesn't exist.
- **Draft replacement on IMAP grants** no longer fails when the draft's index entry is deleted concurrently.
- **Inline attachment disposition** (for example, images embedded in the message body) is now preserved correctly in the MIME message when sending on IMAP grants.
