Hi @MarcoMandricardo-1414,
Welcome!
I did do a lot of research about the UCMA 2.0 API, but failed to find any available download link yet as well.
By the way, considering that Exchange Server 2010 had reached its end of support and lack of security fixes may make the server vulnerable to security breaches. So, for better user experience, it is suggested for you to switch to the newer Exchange version for example Exchange 2016 and Exchange 2019.
Thanks for your understanding and support.
