Note:

iQ.Suite for Microsoft/SMTP uses the SMTP Server of the Windows Server operating system as email server. To manage the SMTP Server, the Management Console of the Internet Information Services (IIS) 6.0 is used. If using Windows Server 2022, the IIS 6.0 Management Console may crash in certain cases. For this reason, we cannot support iQ.Suite on Windows Server 2022 even though iQ.Suite itself runs on Windows Server 2022.
