Error when mailing pdf to Outlook 2013 on 2012 R2 RDS

Hello,

I've installed Adobe Acrobat XI (32bit) on Windows Server 2012 R2 (x64)(RDS) with Office standard 2013 installed (32bit).

When opening a PDF file and email this file i get the following error:

Sometimes when re-create the outlook (exchange) profile, it works.

Can someone help me out?

Thanks in advance
