PST facts
Mac Outlook saves mail in OLM, and Windows Outlook opens PST only. This tool bridges that gap and keeps the exact number of emails along with their unread status.

What Drives Mac Mail Into PST
A Windows Outlook profile cannot open an OLM file. Once the Mac data sits in a PST, it imports into Outlook on a Windows PC with folders in the same order.
Core features
Install, add the OLM archive, preview and save as PST.
Load
Launch the software on Windows, choose Open and Email Data Files, then select Mac OLM File. Upload the archive to the dashboard.
Folder selection
The preview pane lists every file from the archive. Folders and items stay in their original order.
Message preview
Four views open every email in depth before export, which helps IT admins confirm the data.
Selective backup
Filter by name, subject, To, From, Cc or Has attachments, then export the selected data only.
Output options
Select PST in the export options and click Save to start the OLM to PST process. The same menu offers EML, MBOX, PDF, CSV, TXT and cloud upload.
Before converting
Three habits keep the PST import smooth.
Source file
Export the OLM from Mac
Run the Outlook for Mac export on 2011, 2016 or 2019, then copy the resulting OLM file to the Windows computer.
Item scope
Choose full or filtered
Convert the entire mailbox in one go, or filter by name, subject and attachments for chosen mail only.
Cloud option
Think about direct upload
The IMAP option stores OLM data straight into 100+ web mail clients, so no PST step is needed.
The Mac side of the export is covered in Outlook for Mac export to PST and Import OLM to Gmail accounts.

Outlook for Mac can export some items to a file, but it never produces a Windows PST. That gap calls for a bulk tool. The table compares both paths.
| Task | Manual export | Tool |
|---|---|---|
| Cost | Free | $99 one time |
| A few emails | Export from Mac Outlook | Works too |
| Windows PST output | Not possible | PST in one run |
| Mailbox size | Slow on large data | Terabytes in one go |
| Folder hierarchy | Often reshuffled | Exact email counts |
| Contacts and notes | Separate exports | Converted with mail |
| Filters | Mail search only | Name, Subject, To, From, Cc |
| Cloud upload | Not offered | Gmail, Office 365, IMAP |
A Mac can finish only the green row alone.
Contacts can also go to a spreadsheet, as shown in Convert OLM to CSV files .
