Get email from exchange using EWS (Business Applications v2 Content Pack)


I am trying to use the "Get Email List" operation under

Bussiness Applications [2.0.0]\Library\Operations\Exchange 2010 and 2013\Emails\Get Email List

I get the error below about OO not finding the "Microsoft.Exchange.Webservices" dll

I installed the EWS API 2.0 from microsoft:

I was also reading a document I found online (for OO 10.10) and it said that because this is not licensed, it needs to be manually updated, however I dont know how to do it..

Does anybody know where do I need to copy this dll??
