请在客户计算机的注册表编辑器里添加以下键值(先删除该客户端的OAB文件):
HKEY_CURRENT_USER\Software\Policies\Microsoft\Exchange\Exchange Provider
"Limit SRS Incremental Download"=dword:00000000
"Limit Manual OAB Download"=dword:00000000
"Limit SRS Full OAB Download"=dword:00000000
"Allow SRS Full OAB Download"=dword:00000000
您也可以通过组策略统一对客户端进行限制。
