之前装好Exchg并且验证了收发功能好用，做好ghost，过几天后再恢复回来，发现系统不能收发邮件了，找了些资料，总结成以下三点，完事后，收发自如！
1. Exchange Management Console->Server Configuration->Hub Transport->Default Test->Properties->Permission Groups->[Check]Anonymous users
2. Exchange Management Console->Server Configuration->Exchange Certificates->[Renew all the Certificates]
3. Exchange Management Console->Microsoft Exchange On-Permises->Data is unavailabe. Click here to access the latest data->Next->Collect->Finish.
