An error caused a change in the current set of domain controllers - Exchange 2010

After demoting some domain controllers, Exchange was functional and healthy, but we were seeing the occasional error when loading recipient lists, or drilling into a specific mailbox's settings such as below:

This error is caused by GUI caching, more specifically MMC caching. This occurs when a DC (domain controller) that is either unreachable or has changed in some way is still cached by the MMC applet.

To fix this issue remove or delete the Exchange Management Console cache file during it is closed:
Delete this file: "c:\users\<specific user>\appdata\roaming\microsoft\mmc\Exchange Management Console"

This completely worked and we no longer receive the above errors.
