删除exchange2010公用文件夹数据库

卸载ex10出现了问题，公用文件夹数据库未迁移或删除。
The public folder database "XXXX" contains folder replicas. Before deleting the public folder database, remove the folders or move the replicas to another public folder database. For detailed instructions about how to remove a public folder database, see http://go.microsoft.com/fwlink/?linkid=81409.

此时需要删除公用文件夹中的公用文件夹，执行以下两步便可删除

1: Get-PublicFolder "\" -Recurse -ResultSize:Unlimited | Remove-PublicFolder -Recurse -ErrorAction:SilentlyContinue
2: Get-PublicFolder "\Non_Ipm_Subtree" -Recurse -ResultSize:Unlimited | Remove-PublicFolder -Recurse -ErrorAction:SilentlyContinue

最后，再执行删除公用文件的命令即可

Get-PublicFolderDatabase | Remove-PublicFolderDatabase
