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.
Details:
Updated November 20, 2024: We have updated the content with additional resources
Outlook Data Files (.pst) or Personal Storage Tables files contain Microsoft Outlook user messages and other Outlook items (contacts, appointments, tasks, notes, and journal entries) saved in local files on each user's computer.
With this rollout, the first phase of support for .pst files in the new Microsoft Outlook for Windows will provide read-only access to Mail items in .pst files. Users will be able to open .pst files, read their e-mails in .pst files, and search .pst files for e-mails. All Calendar, Contacts, and Tasks data are saved in .pst files, but cannot be accessed in this preview. In future releases, we will expand the support for PST support capabilities.
