What it does

This user setting for automatic migration is enabled by default. If you enable this policy, the user setting controlling automatic migration is enabled. Automatic migration to the new Outlook app is allowed, and the user cannot change this setting. If you disable this policy, the user setting controlling automatic migration is disabled. Automatic migration to the new Outlook app is not allowed, and the user cannot change this setting. Note that this user setting is not available for migration initiated via the 'Admin-Controlled Migration to New Outlook' policy.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
