# Scheduler Configuration and EWS event update fixes

Source: https://developer.nylas.com/docs/changelogs/2026-08-31-scheduler-and-ews-fixes/

## Fixed

- **Scheduler Configuration requests** that send an empty array for `appearance` or `scheduler.additional_fields` are now accepted instead of rejected, so clearing those fields no longer requires omitting them from the request entirely.
- **Event updates on EWS (Exchange Web Services) grants** are now retried when the provider rejects the request due to a stale `ChangeKey` (Exchange's per-object concurrency token), instead of surfacing the conflict as a failure. This reduces intermittent update failures on EWS calendars caused by concurrent changes.
