Hi,This issue can in most cases be resolved by following the below steps: - Log on to the respective Exchange 2007 Server- Click Start > Run and type Regedit- Drill down to HKEY_LOCAL_MACHINE\SOFTWARE\Mi­crosoft\Microsoft Integration- Delete the key: 13F9F3AF-9463-4492­-854A-191CCC441FDBTry again Regards from www.windowsadmin.info

Hi There, If you are able to see exchange tab in User's properties, it mean exchange 2003 management tool is installed on the server. Please uninstall the same. Exchange Tabs are the schema extensions when you install exchange 2003 and Exchange 2003 is not supported on Windows 2008 server. Thanks.

Hi Ramos, First, please note it's not a supported scenario to upgrade the OS where Exchange lives. Upgrade DC to newer version is supported. In Exchange 2007, by default, there is no Exchange tab in ADUC, I guess you ever install Exchange 2003 management tool before, right? The Exchange 2003 management tool is not compatible with Windows Server 2008, so the behavior you described is expected. In order to fix the issue, we need to unregister the related dll file. Please run the following command: regsvr32 /u \windows\system32\maildsmx.dll If it fails, please try to register it and unregister it again. Then please test if the tab is removed. Thanks, Elvis
