It’s very common among Mac users to expect everything to be accurate and perfect. A common problem is arising these days for Mac users in switching from Outlook to Apple Mail. It’s a big problem for them because Outlook installed on a Mac OS supports OLM files, and Apple Mail is compatible with EMLX files. So, if you are in the same trouble, then you can explore various ways to convert OLM to EMLX. Either you can try the manual procedure for switching between these two clients, or you can directly use the Cigati OLM Converter. Before we directly tell you the process, you must know a little more about these two files.

What are OLM and EMLX Files?

OLM files are created on Outlook, that are installed only on Mac PCs and laptops. They store the major mailbox items like emails, attachments, calendar, notes, contacts, etc.. But the shortcoming of the OLM files is that they can’t be accessed in any other email client except Outlook for Mac. You can’t even open them in Outlook installed on a Windows device.

EMLX files are usually created on Apple Mail on a Mac device. This file format saves individual email messages. This file stores only one email with its whole content. Therefore, these files are small in size and are easily manageable.

Now, you check the need to convert Mac OLM to EMLX with all mailbox items.
