You can convert an OLM file to PST by scanning the Mac Outlook mailbox, previewing its contents and exporting the data in a format supported by Windows Outlook.
Which method should you use?
If you want to avoid manually transferring mailbox data, you could try TrustVare OLM to PST Converter. It supports OLM to PST conversion without requiring Outlook to be installed on the computer used for conversion.
1. The process is straightforward:
2. Load: Select the OLM file saved from Outlook for Mac.
3. Preview: Check the mailbox folders and emails before exporting.
4. Convert: Choose PST as the output format and select a destination.
5. Verify: Open the resulting PST in a compatible Outlook environment and check important emails and attachments.
My advice is to test the free demo first. It lets you preview the mailbox and export 10 items per folder, giving you a chance to inspect the results before converting the complete mailbox.
