Send email (Exchange) Error: can not load assembly

[geirmat]

Hello
I try to use the action: Send E-Mail with Attachments (Exchange), but execution fails with message:

Exception: Could not load file or assembly ‘Microsoft.Exchange.WebServices, Version=15.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35’ or one of its dependencies. The system cannot find the file specified.

Any server setup required to give the SharePoint environment access to Exchange?

Thanks
Geir
