Export Mac Outlook to Mac Mail, here is the possible ways as well as why you should try the third party tool for it.
Export Mac Outlook to Mac Mail
Outlook in Mac and Mac Mail are both popular email clients for Mac operating system. Despite that, neither of the client has any way to move the emails data across each other. Nor is there a file that you can use with both clients.
Method 1
Here’s one common method many users implement to export Mac Outlook to Mac Mail:
- Drag a folder from Outlook Mac into Mac desktop
- This converts the folder into *.mbox files
- Start Mac Mail and import the MBOX files from the step above
Remember that the MBOX files you get from this method are not standard MBOX files, even though they have MBOX extension. Also, this approach only works for emails and not for contacts and calendar folders.
Another drawback of this common method should be very obvious: it is very time consuming because you need to do it for each individual folder one at a time. You cannot drag the entire mailbox account to desktop and convert them to MBOX. You need to drag one folder at a time.
Method 2
Another way to export Mac Outlook to Mac Mail is to sync the emails using an email account like Gmail. It goes something like this:
- add an email account and sync the data from Outlook Mac to the servers of that email account (for example: Gmail)
- Add the same email account to Mac Mail and this time sync the data in the opposite direction: from the servers to Mac Mail.
This method doesn’t need any third-party tool and there’s no need to deal with the files. However, the drawbacks of the method outweigh any benefit you might see with it. The biggest drawback is, if your database is huge, a free Gmail or any other email account might not be able to store all of it on the servers. Gmail only offers 15 GB storage and other email providers even less. So, if that’s the case, you would need to perform the above steps multiple times.
In practice, the method to export Mac Outlook to Mac Mail using an IMAP based email account is daunting, time consuming, and seldom produces accurate results.
Method 3
Finally, the method that many experts use for exporting emails and contacts and calendar data from Mac Outlook to Mac Mail is by converting the data files from Outlook, called OLM. This is by far the most efficient and quick approach to export data to Apple Mail. But for this, you also need a professional and safe OLM file converter. Sadly, any random file converter from the internet won’t be cut out for this job and a poorly designed tool might make the matters even worse.
This is where “OLM Extractor Pro” truly outshines every other software app or method that you can think of.
OLM Extractor Pro – the best solution for it

It’s a tool from USL Software that can convert Outlook Mac OLM files to many other formats including Mac Mail. There are two distinct and separate options that delivers essentially the same outcome: you can either convert OLM to Mac Mail Profile directly or to MBOX files, and then import MBOX to Mac Mail.
For those who are looking to export emails only to Mac Mail, we highly recommend the first option. But if you also want to relocate some of the data to clients like Thunderbird and Postbox and other types of software utilities, converting OLM to MBOX can be used, as MBOX is a generic file that works with many different platforms.
Export emails with contacts & calendars as well
“OLM Extractor Pro” is not only used for moving emails but also contacts and calendar. When you select the OLM files you want to convert, the tool gives you an option to either convert everything or filter out types of folders, such as emails, contacts, and/or calendar. After that, it automatically converts the emails to the chosen format and contacts to VCF and calendar to ICS files. There’s also an addition option that you are going to love if you have a lot of contacts and appointments in calendar, which is, to merge or consolidate all of them per folder into a single file. For example, you can choose to merge all contacts from every folder into a single VCF file, instead of converting each entry in the address book to an individual, single VCF file. The benefit of consolidating data in such a way should be obvious to anyone who has managed a large number of such contents. It is much easier to manage and organize information than if you had multiple files.
VCF and ICS files are short form of Virtual contact file and iCalendar file. These two formats (for contacts and calendar, respectively) can be used with many other types of software clients or apps that are used for such information, and therefore, adding a lot of flexibility to the whole process.
The inner processing of the tool
The set of algorithms that execute the conversion and handling of actual data and metadata – are devised with meticulous attention, so that none of the components are left behind or not handled with precision. Whatever there is your selected OLM files will be converted to Mac Mail – including graphical data, MIME attachments, Unicode text in headers, HTML formatted emails, emails in conversational hierarchy, structure of your folders, and so on.
