The route

PST to MBOX in 3 steps

№ 01Step
Export a PST from Outlook
In classic Outlook for Windows go to File → Open & Export → Import/Export → Export to a file → Outlook Data File (.pst), pick the account with “Include subfolders” checked, and save. If you already have .pst files (archives or old data files), you can use those as they are.
№ 02Step
Upload and see the price
Start a conversion, choose MBOX as the result and drop in your .pst files. 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

PST → MBOX questions

How do I get the mail into Gmail?

Gmail can't import MBOX files directly. Add your Gmail account to Thunderbird, import the MBOX files into a local folder with ImportExportTools NG, then drag the folders into your Gmail account and Thunderbird uploads them over IMAP.

Can I convert an OST file instead?

No. OST files are offline caches tied to one Outlook profile, and we don't accept them. Export a PST from Outlook (File → Open & Export → Import/Export → Export to a file) and upload that.

Do I need Outlook to do this?

Only to create the PST in the first place. If you already have .pst files, you can convert them from any computer with a browser.

Are contacts and calendars converted?

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.

What happens to my files?

Uploads are deleted as soon as your result is ready (unfinished uploads within 3 days), and the result is deleted after 7 days. Conversion is automated and nobody at MoveMyInbox reads your mail.
