  • Deleting the computer account was a big mistake, as you have wiped out a lot of the configuration of Exchange.

    Your best option is probably to call Microsoft support and pay their fee, as you are going to have to disaster recover Exchange. It is not just a matter of adding the server back to the domain, because of the loss of information in the domain connected to Exchange.

  • Hi

    I have CA install in my Exchange server, so I will uninstall my CA right or not?

  • Adding the computer back to the domain isn't likely to assist with the Exchange server configuration. If you had just dropped the server from the domain then it would probably work, but deleting the computer account means that even if you add the computer back to the domain, it is not the same computer as far as the domain is concerned.

    If you have a Certificate Authority on there as well, then you have probably broken that too. My previous advice of calling Microsoft support I still believe is the best option because if you try and fix the problem yourself you may well cause further damage.
