Convert OLM to PST

Outlook for Windows can't open the .olm files Outlook for Mac exports. Upload yours and get a PST that Windows Outlook opens directly, with your folders intact.

Who this is for

The route

OLM to PST in 4 steps

  1. № 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.

  2. № 02Step

    Upload and see the price

    Start a conversion, choose PST 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.

  3. № 03Step

    We build the PST

    Mail folders from the archive become the same folders in the PST. Contacts, calendar items, tasks and notes in the .olm are skipped and counted in your summary.

  4. № 04Step

    Open the PST in Outlook

    Download the .pst and open or import it in Outlook: File → Open & Export → Open Outlook Data File (or Import/Export) in classic Outlook for Windows, or File → Import in Outlook for Mac.

What's kept, and what isn't

We'd rather tell you up front than have you find out after the import.

Kept

  • Folder structure, including subfolders
  • Sender, recipients (To, Cc, Bcc), subject and dates
  • HTML and plain-text bodies
  • Attachments with their original file names, and inline images
  • Read, unread and flagged status
  • Full original headers, so threads and replies work in Outlook

Not included

  • Contacts, calendar events, tasks and notes in the .olm (skipped and counted in your summary)
  • Outlook for Mac rules, signatures and account settings
  • Categories and colour labels

FAQ

OLM → PST questions

Can Outlook for Windows open an .olm file?
No. .olm is an Outlook for Mac format. Outlook for Windows only opens .pst files, which is why the archive needs converting.
How do I export an .olm from Outlook for Mac?
In legacy Outlook for Mac choose Tools → Export (or File → Export in some versions), select Mail, choose Continue and save the .olm file. Microsoft documents this export only for legacy Outlook for Mac.
Are contacts and calendars converted?
No, only mail. Contacts, calendar items, tasks and notes in the archive are skipped and the summary tells you how many were left out.
My .olm is very large. Is that a problem?
Each conversion can be up to 50 GB, and the price depends only on size. Use a wired connection for big uploads; once the upload finishes you can close the tab.
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.
