Information about us

Exchange4U is a project of PoInter Ltd. company. It was opened in 2005 by two experts on the realm of Microsoft Exchange Server, building WAN networks and supporting hundreds of users.

Ing. Miroslav Knotek, one of the best consultants in the realm of Microsoft Exchange Server in the Czech Republic, graduate from The University of Economics, Prague, major in ASP (Application Service Provider) and Ing. Jan Kořán with a five-year experience in the realm of design and support of extensive networks on the base of the MS servers in USA.

The absence of an affordable solution on the base of MS Exchange Server on the Czech market requested to find out a way how to declassify this service to smaller companies in the Czech Republic without the necessity for investments of hundreds of thousands. ASP, mailbox hosting on an adequate Exchange Server for a low fixed payment tariff is a common world wide solution for smaller companies. At companies with less than 50 mailboxes, it is demonstrably the most economical way of using all advantages of the MS Exchange Server. That is possible thanks to the Microsoft’s license policy which enables ASP providers to pay licenses only for active accounts as well as thanks to the splitting fixed costs for the MS Exchange Server purchase and implementation between more companies.

What’s ASP (Application Service Providing)?

The organization ASP Industry Consortium considers ASP such company, “...which provides application, IT infrastructure and other additional services necessary to offer complete application services on the base of subscription to the customer. ASP typically hosts an application in its remote data center and the access of its customers is enabled via the internet or private lines, possibly through Virtual Private Network (VPN).”
