Mac Mail to Outlook

Mac Mail to Outlook: Ultimate Guide

Email is the fixture of office life, and the range of systems is stunning. Still, Outlook is the default choice for many companies and users. First, it is secure. Secondly, it has flexible scheduling and task assignment. Thirdly, it facilitates collaboration. Here is everything you need to know to switch from Mac Mail to Outlook.

If you are reading this article, you probably need a method for quick and error-free transfer. Do not look any further: we have summarized all popular approaches. You will see that automatic tools win hands down. The collection of guides and software on OutlookTransfer covers the full spectrum of needs. The Mac Mail vs. Outlook scenario is common, but it is also complex.

Fundamentally Different Languages

Obviously, you cannot just drag and drop files between windows, as you have different OS. Moreover, if you copy your files to the Windows computer, direct import is still impossible. Every mail client uses one or more specific formats to save data. The Apple-based system saves data as MBOX and EMLX. Meanwhile, Outlook is based on PST. That is how it stores messages and other items, such as contact details. These extensions are incompatible.

Can I Do It Manually?

Yes, but only when two conditions are met. First, you need to have sufficient time, as the procedure is lengthy. Secondly, you should be ready to accept minor or major corruption or loss of data along the way.

Sadly, inaccuracy is the biggest drawback of any mail method. Only a third-party tool can guarantee precision. Besides, there is no direct way to simply import MBOX into Outlook. You may (or may not) succeed without it if you have additional mail software.

Migration via Eudora and Outlook Express

As you can see, this method requires two more systems. After your data is moved between the programs, it is finally converted into PST. This is a multistage process with four stages:

  1. Extraction of data from Mac Mail;
  2. Creation of an *.mbx file;
  3. Importing of data into Outlook Express;
  4. Exporting to Microsoft Outlook.

Stage 1: Extract Data from Mac Mail

  • Use the ‘File’ menu in Apple Mail to import your mailboxes;
  • specify MBOX as the desired format;
  • navigate to the MBOX file on your Apple device;
  • choose MBOX and proceed further;
  • click ‘Done’ to finalize the process.

Stage 2: Modify the Type

Now, you need to feed the data into another mail client — Eudora. This app for Windows can recognize your data and modify it. It will become readable for Outlook Express, which will make it readable for Outlook. Here is what you should do:

  • left-click on the file and replace their extension with .mbx;
  • move it to Eudora’s directory (use the following path: C:\Documents and SettingsApplication Data OualcommEudora);
  • launch Eudora;
  • select the file;
  • close the application (the file will be created).

Stage 3: Import to Outlook Express

This outdated system may still be used for conversion purposes. From the ‘File’ tab, you can access import for messages. Specify Eudora as the source and browse to the file created in Stage 2. Finalize the process.

Stage 4: Final Import

After your files land in Outlook Express, you export them to Outlook. Open the latter and head to ‘File’. From there:

  1. Use the ‘Open’ section;
  2. Choose import/export;
  3. Choose import of internet mail and addresses;
  4. Specify Outlook Express as the source;
  5. Put a tick in the Import-Mailbox checkbox.

That’s all! As you can see, the process is cumbersome and time-consuming. You need to have four different mail systems installed at the same time. This is not the only method, but the alternatives are also drawn-out. Instead of moving your mail back and forth between them, why not use a universal tool? It may complete the transfer in seconds.

Automatic Tools: Overview

Use powerful yet lightweight software designed especially for the Mac Mail/Outlook pair. All of your messages and attachments will remain intact. If you are using version 10 or newer, the tool will even scan your machine for the source files. All you need to do is launch Mac Mail and:

  • right-click on the necessary source folder to export it;
  • specify the destination;
  • repeat for any other folders;
  • copy or move the output to your Windows computer;
  • use the transfer tool: choose the source, specify the output format, and wait for completion!

The utility has a clear user-friendly interface. You can feed the mail directly into your Outlook profile, create separate EML files or a single file with the PST extension. The third option allows you to move the information to another computer (for example, your office PC) and import it there.

The Bottom Line

Seamless transfer of Mac Mail to Outlook is impossible without third-party tools. Precision is guaranteed. Top solutions are simple, well-designed, and efficient. Even a beginner can manage!
