You can only export Mac Outlook items as an .olm file, which can only be imported into Outlook on Mac, or with third-party software if it’s on another app.
- On the Tools tab, choose Export.
Note: Don't see the Export button? There are two ways to check. - Make sure you are using the legacy version of Outlook. On the Outlook menu, check the upper right side of the Outlook Window and see if there is a checkmark or a toggle beside Legacy Outlook. Select it and wait for Outlook to restart in Legacy mode.
- Additionally, in some versions of Mac OS, you may find the Export option under the Outlook File menu.
- In the Export to Archive File (.olm) box, check the items you want to export, and choose Continue.
- In the Save As box, under Favorites, choose the Downloads folder, and click Save. This will export all checked items - all your calendar data and additional data like emails if you choose.
- Once your data has been exported, you'll get a notification. Choose Finish.
