无法删除Exchange 2007中的公用文件夹

我正在尝试删除Exchange 2007 SP2邮箱服务器上的公用文件夹数据库，以便删除该angular色。 我使用Exchange附带的PowerShell脚本（MoveAllReplicas.ps1）将副本迁移到另一台服务器。 我证实他们在那里，并删除这台服务器上的副本。 但是，有五个，似乎都与Outlook 2003有关，只要我尝试删除它们，就会给我这个错误：

-------------------------------------------------------- Microsoft Exchange Error -------------------------------------------------------- Action 'Remove' could not be performed on object 'SCHEDULE+ FREE BUSY'.

我受到时间限制，所以我希望有人能帮助我。
