How to Export Outlook for Mac to Apple Mail

You cannot just drag and drop to import Outlook to Mac Mail. The Import feature does not work for this, either. Whether it is ways to convert Outlook for Mac to Apple Mail, or vice versa, you need to be extra cautious. Users now have to modify file extensions to succeed. Even within the same operating system, mail clients clash, which prevents exporting Mac Mail to Outlook for Mac.

Stage 1: Replicate V2

You need to locate a folder titled either V2 or V6 (depending on the Mac version). Make a copy of it on your Desktop. If you are not sure how to find the location, use the ‘Go’ option of your finder menu. From there, pick “Go to Folder” and type the required path. It looks like this: ~/Library/Mail/

As a result, you should now see the folder. Move it to your Desktop via drag-and-drop. Remember to keep the Option key pressed throughout the operation. This way, a copy will be generated and pinned to your Desktop. Do not forget to check that the original file is intact! Otherwise, you may be unable to restore your correspondence if a glitch occurs.

Stage 2: Relocation

Open the newly generated copy of the folder. Proceed to the Spotlight search feature located on the top on the right-hand side. Next, you can look for the mail data files in the folder.

  1. Enter ‘.emlx’ (which is the mail storage format for Mac Mail).
  2. A list of messages stored in is displayed.
  3. Return to the Desktop.
  4. Generate a new folder and name it accordingly — e.g., “MailCopy”.
  5. In the window, select all items and drag them to the folder in 4.

Stage 3: Assigning Names

Readability in Outlook requires renaming. Every filename is compound: it contains a name and extension separated with a dot. Alter the extensions by renaming the files. Luckily, you do not have to work with each one separately.

Select the entire group in the “MailCopy” folder, and right-click on it. In the menu, choose “Rename Y Files”. Now, the Finder feature will alter the endings collectively. The endings must be switched from *.emlx to *.eml.

Unless you use the IMAP server, there is only one step left to migrate Apple Mail to Outlook for Mac! Finally, you can easily move the altered files — just drag and drop. You may be frustrated to find that the folder structure is not recreated automatically. Hence, be prepared for some tidying up.

Vice Versa: Outlook in Mac Mail

  1. Create a folder (e.g., Copied Mail) on your desktop.
  2. Open Outlook and drag the desired folder into Copied Mail. The copied files will now have the *.MBOX extension.
  3. Open Mac Mail and use the ‘Import mailboxes’ feature.
  4. Choose ‘Select files in Mbox format’ and ‘Continue’.
  5. Choose the right source and click ‘Done’.
