The route

OLM to MBOX in 3 steps

№ 01Step
Export an .olm from Outlook for Mac
In legacy Outlook for Mac choose Tools → Export (in some versions File → Export), tick Mail in “Export to Archive File (.olm)”, choose Continue and save the file. Microsoft documents .olm export only for legacy Outlook for Mac, not the new Outlook.
№ 02Step
Upload and see the price
Start a conversion, choose MBOX as the result and drop in the .olm file. The price depends only on the total size, and you see it before you pay. Uploads go straight to encrypted storage.
№ 03Step
Import the MBOX files
Unzip the download. In Apple Mail use File → Import Mailboxes. In Thunderbird install the ImportExportTools NG add-on, right-click a local folder and import the mbox files. To get the mail into Gmail, import into Thunderbird first, then drag the folders into your Gmail (IMAP) account.

FAQ

OLM → MBOX questions

What do I get?

A zip with one .mbox file per Outlook folder, keeping your folder names and nesting. MBOX is plain text and readable by Apple Mail, Thunderbird and many other apps.

How do I import the MBOX files into Apple Mail?

Unzip the download, then in Apple Mail choose File → Import Mailboxes, pick the files and follow the prompts. Imported mail appears in a new mailbox called Import.

How do I import them into Thunderbird?

Install the ImportExportTools NG add-on, right-click a folder under Local Folders and use its Import mbox file option. Import into a local folder, not directly into an IMAP account.

Are contacts and calendars included?

No. Only mail is converted. Contacts, calendar items, tasks and notes are skipped and counted in your summary.

How much does it cost?

One price per conversion, based on the total size you upload, the same tiers for every format. You see the exact price before you pay, and there is no subscription.
