Open Outlook for Mac OLM files on Windows

What’s in an OLM file

Everything Outlook for Mac exported: the mail in every folder, with attachments, and the calendars, contacts, tasks and notes. MailTrove shows all of it, the mail in its folders and the rest in views of their own.

Open an OLM file

1. Get MailTrove from the Microsoft Store. It's free to download.
2. Choose File > Open and pick the .olm file, or drag it onto the window.
3. Browse the folders and read the emails, with their attachments.

Still on the Mac? In Outlook for Mac, choose File > Export to save the .olm file, then copy it to your PC.

Move the mail somewhere else

Outlook for Windows has no way to import an OLM file. With the full version, MailTrove exports folders, or a whole archive, to one MBOX file or to EML files, which Thunderbird, Apple Mail and many other email apps import. It also exports to PDF for keeping, and saves attachments on their own.

Search it first

The full version searches every word of every email in the export, attachments included, so you can find what you need before deciding what to keep. Operators narrow it down: from:, subject:, has:attachment, before:2019 and more.

Free to start

The free version lists every email in the OLM file and reads the 10 newest in each folder. The full version reads everything and adds full search, conversations and export, for $29.99 once (plus any tax). Nothing is uploaded: the file is read on your PC and never changed. See pricing.

Get MailTrove

Free from the Microsoft Store, for Windows 10 or later. A Mac version is coming to the Mac App Store.
