公用文件夹同步问题

neol

三台邮件Exchange2003服务器S1 、S2和S3在同一个域mail.com中，S1是前端服务器，其上没有邮件和公用文件夹存储，它只负责把一个POP3或OWA访问请求转发给正确的后端服务器。S2和S3是后端服务器存有用户邮箱和公用文件夹。<br>
S2（后端）<br>
<br>
S1（前端）<br>
<br>
S3（后端）<br>
当在S2上建立一个公用文件夹file1时，做Replication到S3后，<font color="red">发现S3上并未出现需要同步的文件夹file1</font>，如果在S2的system manager中打开public floder点击file1在status中单击右键，手动同步内容，S3则会报错：见附件<br>
<br>
目前S3上应用程序日志中报错如下：<br>
Error updating public folder with free-busy information on virtual machine S3. The error number is 0x80040115.<br>
更详细的解释如下：<br>
