Using the New Outlook for Mac features in business environments
Thank you for reaching to Microsoft Q&A regarding your inquiry.
Outlook for Mac does not natively support creating or exporting to .pst files, which are primarily used by Outlook on Windows. Instead, it uses .olm files for archiving and exporting data like emails, contacts, calendar items, tasks, and notes. This is a longstanding limitation, as .pst is a Windows-specific format.
This is the closest equivalent to creating a .pst file and will back up your information for storage or transfer. Ensure you're using the legacy (classic) version of Outlook for Mac, as the "New Outlook" interface (a toggle in newer builds) may not have the export option. For the specific steps, you can refer to: https://support.microsoft.com/en-us/office/export-items-to-an-archive-file-in-outlook-for-mac-281a62bf-cc42-46b1-9ad5-6bda80ca3106
This .olm file can be imported back into Outlook for Mac if needed. For reference, Outlook for Mac can import .pst files (e.g., from Windows), but not the reverse. https://support.microsoft.com/en-us/office/import-email-messages-contacts-and-other-items-into-outlook-for-mac-6cc48404-a65c-4b8c-a12a-95a905249414
