Template:Notice Windows XP and Windows Server 2003
Important notice for Windows XP and Windows Server 2003 users:
As Microsoft does not provide .NET Framework 4.5.1 for Windows XP and Windows Server 2003, the last MailStore version that can be installed on these platforms is version 8. Contrary to the official Update and Support Service terms, you are eligible to continue using MailStore Server 8 on the above platforms until the end of extended support (July 14, 2015) for Windows Server 2003.
In a mixed environment, Microsoft Outlook users are able to use MailStore Outlook Add-in 8.1.3 to connect to MailStore Server 9.
