Groupwise 2014R2 in combination with CMDB software Topdesk

Are there people or companies wich use Groupwise 2014R2, and have made a connection to Topdesk. We use Topdesk, a service management tool for our CMDB of all desktop, laptop and mobile devices. Also we register issues here, What this Topdesk product have, is default a possibility to make a connection with Exchange e-mail. So the planning in Topdesk, comes also in the calendar from exchange mailbox. Now we are looking for a possibility, or experience from someone. That this also can be done with Groupwise. Is this possible, and have anyone experience with that?

kind regards, HKO
