Now in the SharePoint 2010 days, this problem has been resolved in the "MWSDefaultv4.master" master page. This is the standard master page that is used for meeting workspaces. When you want to make use of the "v4.master" like I did, the same problem occurs as in SharePoint 2007.
The solution is still the same, only the version number has changed.
- Add the following line of code to the v4.master page.
XHTML1<%@ Register Tagprefix="Meetings" Namespace="Microsoft.SharePoint.Meetings" Assembly="Microsoft.SharePoint, Version=184.108.40.206, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
- Add the following line of code after the body tag.
