Hi Drltaop,

Thank you for your question.

Did you mean you install Exchange 2010 on Window server 2012 R2. By my learning, Exchange 2010 didnt support Window server 2012 R2, we could refer to the following link:

if not, you could refer to the following link:

If there are any questions regarding this issue, please be free to let me know.

Best Regard,
