I was in the same boat where i have to migrate my mails (1.5 GB) from MacOutlook2011 (olm) to outlook 2010 ( pst)
after hours of serach i was able to convert all my olm mails to pst format . this is what i did , do exactly the same, do not deviate from any of the steps
1. from your outlook 2011(mac) drag the folders to a location (i drag it on my desktop). this will create a mbox file
2. open your mail app on mac and import the mbox files cretaed in step 1
3. once step 2 is done , export the mails from mail app in mbox format
4. there is a difference between mbox format created in step 1 and step 3
5. install thundirbird and also install a addon known as importexport tools in thundrirbird
6. import the mbox folder creted in step 3 in thunerbird using importexport addon
7. once step 6 is done export the folder from thunbird in eml format in a folder using importexport addon
8. go to windows and install windows live mail from windows essential pack
9 import the folder created in step 7
10. after step 9 export mail from windowslive mail to in exchange format
11. open up your windows outlook and you shuld see all your mail in folder name storage
and thats it , its time consuming but will save you some beer money,
