Exchange Management Tools won’t uninstall

When attempting to uninstall the Exchange 2010 Management Tools you receive an error message which says:

“Some controls aren’t valid. Please specify an existing server role(s) to uninstall.

To work around this issue and be able to uninstall the Exchange 2010 Management Tools you will need to use the command line.
1.Run the Command Prompt as ‘Administrator’

2.Navigate to your Exchange install path, for example
2007: C:\Program Files\Microsoft\Exchange Server\Bin
2010: C:\Program Files\Microsoft\Exchange Server\V14\Bin

3.Run this command /mode:uninstall /role:MT

4.The uninstall process will begin to automatically uninstall each of the Management Tools components.

5.When complete you will see ‘The Microsoft Exchange Server setup operation completed successfully’

Disable Exchange cached mode per Computer, not per User?

You can create a GPO that applies to those computers and enable GPO loop-back processing.

To set user configuration per computer, follow these steps:

  1. In the Group Policy Microsoft Management Console (MMC), click Computer Configuration.
  2. Locate Administrative Templates, click System, click Group Policy, and then enable the Loopback Policy option.
