Removing a non-functional Exchange 2010 server from the network

Hello.  




We are running the following environment.

Domain Functional Level: Windows Server 2008 R2

Forest Functional Level: Windows Server 2008 R2





We have two Domain Controllers

Windows 2012 R2

Windows 2016 Standard Server




The 2012 server is running Azure AD connect to synch with O365.




We have a server running Windows 2008 R2 with Exchange 2010.

We no longer use the on-premises Exchange server, because we have moved to Office 365.

We need to remove Exchange, remove server from the domain and shut it down.


However due some recent changes, we are having problems with this server with Exchange Services no longer starting and Shell cannot connect to AD.

Consequently I am unable to perform a clean removal of mailboxes, database, and uninstall Exchange.




What are my options.  Can I remove the existence of the Exchange components from ADSI?  If so, what exactly will I need to remove?




Thanks in advance.




Regards,

Real-Timer

If you migrated to O365 then are they configured using a hybrid between 2010 and o365?
Or just did a cutover migration?

Well yes ADSI is the option and shut it down

HI,

Always the only supported uninstallintion it is to remove from Programs and features...but in your case since you are not able to access Exchange. You need to remove from ADSI edit.
