Overview

This article provides an answer to the query: Can GFI MailEssentials be installed on a Microsoft Exchange Server with another VSAPI product?

Information

Microsoft Exchange Server supports only one Virus Scan Application Programming Interface (VSAPI) registered product at a time. GFI MailEssentials will throw a warning during installation and will not unregister the currently registered VSAPI scanning product. In order for you to use GFI MailEssentials VSAPI scan, the third party VSAPI scanner must be removed from the server.
