Stellar Converter for OLM – a Complete Overview



Stellar Converter for OLM Product Review 0

Microsoft Outlook is easily one of the best email clients we have today, and it’s available both on Windows and Mac. Unfortunately, if you want to migrate from Outlook on Mac to Outlook on Windows, you can’t transfer your mailbox data directly. Even if you are using the same version of Outlook on both platforms, you can’t use your mailbox data interchangeably. This is because Outlook for Mac stores mailbox data in OLM format while Outlook for Windows stores mailbox data in PST.

If you want to transfer your Outlook mailbox data from Mac to Windows, you have to convert your OLM file to PST first. Stellar Converter for OLM software is designed for this specific purpose and it makes the migration easier.


Stellar Converter for OLM allows you to migrate from Outlook for Mac to Outlook for Windows by converting your OLM into PST. It can convert all your items stored in an OLM file such as emails, calendars, notes, etc. into a PST file in a few simple steps.

To use Stellar Converter for OLM, you need to follow these steps:

  1. Launch the software and provide the location of the OLM file. After this, the software will scan the file.
  1. Once the scanning is finished, you can preview the items in the OLM file and select the items you want to save in the final converted PST file.
  1. Save the converted file. You can either save a new file or append the data to an existing PST file. You can also use the “Apply Filter” feature to omit certain emails from the OLM file and reduce the size of the converted PST file.
  1. The software now saves all selected items in a PST file.  

As you can see, using the OLM to PST converter is easy. You need to follow just a few steps, but at the same time, you get advanced features such as filters, items preview, and even additional export formats such as HTML and PDF (in Stellar Converter for OLM Technician).

One thing that stands out in the OLM to PST converter by Stellar is its user interface. It makes using the product easy, which in turn, makes Mac to Windows migration seamless. The software also comes with a “find” function, which you can use to locate the OLM file on your system easily.

Stellar Converter for OLM is capable of converting the largest OLM files without any problem. We tested the tool with several OLM files of varying sizes, and the efficiency of the product was satisfactory with all of them. We were also able to use other applications on the system while the converter did its job in the background.
