What Is the Server Error 0x800ccc90?

Windows Live Mail (formerly known as Windows Live Mail Desktop, code-named Elroy) was a Microsoft freeware email client. It replaced Windows Mail in Windows Vista, which replaced Outlook Express in Windows XP and Windows 98. Windows Live Mail is intended to run on Windows 7 and Windows Server 2008 R2, but it is also compatible with Windows 8.1 and Windows 10, despite the fact that Microsoft includes a new email client called Windows Mail with the latter.

WLM was discontinued by Microsoft but a lot of users are still using it. It was the successor to Windows Mail (Windows Vista), which in turn was the successor to Outlook Express (Windows XP and Win98).
