# Availability limits, metadata paging, provider fixes

Source: https://developer.nylas.com/docs/changelogs/2026-10-10-availability-metadata-and-provider-fixes/

## Changed

- **Calendar and Scheduler availability time range.** Requests to [`POST /v3/calendars/availability`](/docs/reference/api/calendar/post-availability/), Scheduler availability, bookings, and group time slots now cap the requested time range at 732 days (about two years). Recurring event expansion is also now bounded. If your integration requests wider ranges, expect the response to reflect this limit.
- **`metadata_pair` pagination** now returns results in a guaranteed order, oldest-tagged first, and paginates with a cursor, so results aren't skipped or repeated when matching objects are removed between pages. Recently tagged objects appear on the last pages. This applies to every `metadata_pair` lookup.
- **The `metadata_pair` "either metadata or provider filters" error** on Messages, Drafts, and Contacts now names the specific filter that conflicts with your query, instead of a generic message.

## Fixed

- **IMAP `COPYUID` responses** are now accepted correctly when the provider's `UIDNEXT` value doesn't advance, improving reliability for IMAP message copy and move operations.

## Added

- **EAS (Exchange ActiveSync) folder management.** You can now create and update folders on EAS-connected accounts.
