Exporting emails from Apple Mail (macOS) to Outlook (Windows or Mac) can be a bit tricky due to different file formats, but it can be done using the following step-by-step process:

Step 1: Export Mailbox from Apple Mail

  1. Open Apple Mail.

  2. Select the mailbox or folder you want to export.

  3. Click Mailbox in the top menu > Export Mailbox.

  4. Choose a location to save the mailbox (it will be saved in .mbox format).

  5. Click Choose.

You now have an .mbox file containing your emails.

Step 2: Convert MBOX to PST Format (for Outlook)

Outlook (especially on Windows) does not support MBOX files. You need to convert .mbox to .pst (Outlook's native format).

Use a Third-Party Converter Tool

  • Tools like Shoviv MBOX to PST Converter, Stellar Converter for MBOX, or SysTools MBOX to PST Converter can help.

  • Install one of these tools.

  • Import the .mbox file and export it as a .pst file.

Step 3: Import PST into Outlook

For Windows Outlook:

  1. Open Outlook.

  2. Go to File > Open & Export > Import/Export.

  3. Choose Import from another program or file > Outlook Data File (.pst).

  4. Browse and select the converted PST file.

  5. Click Finish.

For Mac Outlook:

  • Outlook for Mac doesn’t directly support PST. You may need to use OLM format or import the emails via an IMAP account (explained below).

Alternative Method: Use an IMAP Email Account

If you want to avoid converters:

  1. Add a Gmail, Yahoo, or other IMAP email account to Apple Mail.

  2. Drag your Apple Mail emails into folders within that IMAP account.

  3. Once synced, add the same account in Outlook.

  4. Your emails will appear there automatically.
