+ - **Deprecated 2026-07-17:** Onboarding for Apple Messages for Business is deprecated. New onboarding stops, and the Apple configuration options in Copilot Service admin center are removed on 2026-09-30. Existing configured channels keep working, but don't start a new Apple Messages build after this — you won't be able to finish it. See [deprecation page](https://learn.microsoft.com/en-us/dynamics365/contact-center/implement/deprecations-contact-center).
  - Longest lead time of any digital channel. Apple Business Register registration, MSP selection, and Microsoft Support backend onboarding take weeks before you can touch D365 config. Start Apple onboarding at project kick-off, not during implementation.
  - Two parties must move before you can do anything. Apple approval and Microsoft support escalation are out of your control. Build buffer into the timeline.
  - Authentication and Apple Pay can ship in a second phase: the channel goes live without them, but you'll need them fully configured to use them.
