The new Microsoft Outlook for Windows will offer read-only support for .pst files, allowing users to open, read, and search emails in .pst files. Calendar, Contacts, and Tasks data in .pst files will not be accessible in this phase. Rollout begins late November 2024 for Targeted Release and mid-January 2025 for General Availability. Outlook Data File support is enabled by default but can be managed with the OutlookDataFile mailbox policy.
Applies to: Microsoft 365 apps
