It appears this MP is pulled as well since it doesn’t support updates meaning the previous version has to be removed prior to importing this version. Since Microsoft doesn’t want to put organizations through such an ordeal the MP will be updated in order to support updates.
As stated before there were some issues with the previous version of the Exchange 2010 MP (version 18.104.22.168). These issues were pretty serious which forced the Exchange Team to pull the MP.
Yesterday Microsoft published the newest version of this MP, version 14.03.0038.003 in which the issues are fixed.
MP can be downloaded from here.
