I think there may be a bit of background information you are forgetting to mention. Did you have any issues with active directory lately?

exchange account in AD (Windows 2008 Server)were deleted manually.

The whole idea was to reinstall the Exchange Server from scatch, only to notice that uninstallation was not possible.

I need to remove exchange completely from this server using any means, without a server formating.

thanks

There we go! The more details provided when posting an issue, the easier it is to really understand the issue!

Have you tried running an authoritative restore of the exchange server account from your active directory backup?

In your case, running setup to uninstall exchange will not work because it will not find the server in AD. Unfortunately there is no Manual removal process of exchange 2007 (like they had in previous version)(http://support.microsoft.com/kb/927464). You will also have to remove the computer from the domain and rejoin it so any other (domain related) applications running on it are broken anyways. In short, if you really want to get this done with the least amount of troubleshooting and effort put into Exchange (there may be other reason you do not want to format), the cleanest method, I would suggest:
1. format the whole server
2. Reinstall it with the SAME NAME, SAME OS and SAME drive configuration as it currently sits (basically mirror the server)
3. reconfigure it and run exchange setup with the RecoverServer switch to get its configuration back from AD (http://technet.microsoft.com/en-us/library/aa998656.aspx)

I am not sure what you mean. Do you mean remove the original server from the domain and rejoin it back into the domain? Yes you can do this, but you still have to manually go and give this new computer account permission to the organization (using ADSIEdit) (if that was what you meant!)

You can do it on any new machine but you will want it to contain the same name as the old server which means formatting the old machine or at the very least, change the computername.  It just has to meet what de.blackman stated.  Read this step-by-step article which explains how to use the recoverserver:
