测试中研究了误删仲裁邮件的情况，exchange 2013的修复方法中文资料没有这里补上.
1 运行Get-Mailbox -Arbitration可以看到现在的仲裁邮箱，要重新创建仲裁邮箱，我们首先必须删除所有随附的用户帐户，下图是在CN = Active Directory中的用户
2 可以再次运行Get-Mailbox -Arbitration查看是否全部被删除
3 删除后，必须再次运行Setup.exe / PrepareAD / IAcceptExchangeServerLicenseTerms命令（从正确的安装介质）重新创建仲裁邮箱
4 现在，用户帐户已重新创建，下一步是将其启用邮件：
Enable-Mailbox –Arbitration –Identity "FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042"
Enable-Mailbox –Arbitration –Identity "SystemMailbox{1f05a927-8668-4003-adad-9b80758e86db}"
Enable-Mailbox –Arbitration –Identity "SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}"
Enable-Mailbox –Arbitration –Identity "SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c}"
可以使用另外一个命令启用仲裁邮箱
Get-User | Where {$_.Name –like "SystemMailbox*"} | Enable-Mailbox -Arbitration
Get-User | Where {$_.Name –like "FederatedEmail*"} | Enable-Mailbox –Arbitration
5 之后对邮箱进行名称设置，federation Arbitration邮箱必须设置成1MB的限制容量
Get-Mailbox –Identity "SystemMailbox{e0dc1c29*" –Arbitration | Set-Mailbox –Arbitration –DisplayName "Microsoft Exchange"
Get-Mailbox –Arbitration –Identity "FederatedEmail*"} | Set-Mailbox –Arbitration –ProhibitSendQuota 1MB
6 最后验证一下， Get-Mailbox –Arbitration
