When using Outlook on Mac OS, the mailbox data is saved in an Outlook for Mac (OLM) data file. You cannot import an OLM file directly into Outlook for Windows; you would need to configure your Outlook for Mac email account in Outlook for Windows by using Exchange/IMAP server settings.
But, you may face issues in transferring data from Mac to Windows Outlook if the email account cannot sync with the server. In that case, you need to convert the OLM file into Outlook PST file format.
You can easily convert your Outlook for Mac data file into an Outlook PST file by using an OLM to PST converter tool such as Stellar Converter for OLM.
The software is a quick alternative for converting OLM files into a new or an existing PST using minimal effort. Besides, no technical assistance is required to perform the conversion process; you only need to Select the OLM file, Convert mailbox data, and Save it in PST format.
The best part of the tool is the interface, which is easy to navigate and helps convert OLM to PST file in just a few clicks.
To convert Outlook for MAC data file to Outlook PST file, you need to select the file for conversion by clicking the Browse button. Use the Find option if you are not aware of the file location. Once the OLM file gets selected, click Convert to begin the conversion.

The software may take some time to scan the selected OLM file depending on the size of your mailbox. But that does not matter, as you could continue working on other applications while the scanning is in progress.
Note: You can click the ‘Stop’ button to end the file scanning process (if needed). Doing so will display only the scanned mailbox components. For the conversion of all mailbox components, you will need to rerun the scan process.

Once the software is done with the scanning, it will display a preview of complete OLM file data. You can check the preview of converted mails to validate the converted data.

After validating the mailbox data, save the converted OLM mailbox by clicking Save Converted Mailbox on the Home menu. The software will then display a ‘Save As’ dialog box with multiple file saving options, including PST, MSG, and EML. Choose PST and then click Next.

Note: If you have installed the demo version of the software, you can have a free preview of the converted mailbox items. But, to save these items, you need to activate the licensed version of the software.
When the ‘Save File’ dialog box appears, choose to save the converted file as new PST or add data to an existing PST file/Outlook profile.
Note: Use the ‘Apple Filter’ option for selective conversion of mailbox data.
