Hi I have an old exchange 2007 server Information that appears on the Exchange Organization and I will like to delete all this information to start in new from the beginning with a New Exchange 2007 Installation from my Exchange 2003 organization. My question is the following: Is it possible to delete all information about this server manually? (Because the exchange server does not exist now), Exchange Administrative Group (FYDIBOHF23SPDLT) and Exchange Routing Group (DWBGZMFD01QNBJR). Regards, Asef Liria

Hi guys, I will be off line until Monday, regards

Hi Yes you can uninstall the server from the control panel, that's the best choice If that doesn't work you can install it with same name, ip etc, and then run setup.com /recoverserver and then uninstall it from control panel Last resort would be to delete the server with adsieditJonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

Hi Jonas, I was on vacation until today, so I've been late to respond. Recently I reinstalled the server as you suggested me. now the error is different, but it is related to my action having cleared administrative group (FYDIBOHF23SPDLT) manually using ADSI Edit. How can I fix this problem? Below you will see the installation error. ............ Summary: 4 item(s). 1 succeeded, 1 failed.
