Import Outlook mac archive files in Windows Outlook

Check the file format of your outlook mac archived files. They must be .OLM. This file format is not supported by Outlook for windows while .PST file format is supportive in windows outlook. SO what you can do is, convert OLM files to PST format and import easily your outlook mac archive files in windows outlook. 

For this conversion you need olm to pst converter application, available online.
Here is one  I am aware of and have used personally: OLM to PST Converter

For safety first test the tool by downloading its trial version and after satisfactory confirmation of its proper working go for the full version. As your emails are the more important than these tools to be risked for.

Hope this helps.
