The new Outlook for Windows will soon support managing emails in PST files, including moving, copying, deleting, and categorizing. Rollouts begin mid-January 2025, with general availability in March 2025. PST support will be default, but can be managed with OutlookDataFile mailbox policy. No admin action is required before rollout.
