Sharepoint server – missing DLL error

I get the error message that Microsoft.exchange.webservices can not be added to GAC during deployment of the solution. We have a solution from another team working on their environment. If we try to set up the development environment for it, the above error will be displayed. His Sharepoint 2013 version. What could be the cause? Checked Visual Studio versions and other things already. Any help will be great for that. TIA.
