Hi everyone,
We recently migrated all of our users from Site A to Site B. Now, I'm trying to remove the Exchange mailbox servers that were in Site A, since we're going to be decommissioning the site. All of these mailbox servers have been removed from the cross-site DAG, and all other services have been moved over to Site B as well (mail flow, CAS, etc). However, when I try and uninstall Exchange from any of the seven mailbox servers (I've tried it on two so far, with the same result), I get the following error at Step 7 of 11:
Error:
The following error was generated when "$error.Clear();
& $RoleBinPath\ServiceControl.ps1 DisableServices $RoleRoles.Replace('Role','').Split(',');
& $RoleBinPath\ServiceControl.ps1 Stop $RoleRoles.Replace('Role','').Split(',')
" was run: "Service 'Microsoft Exchange Information Store (MSExchangeIS)' cannot be configured due to the following error: The specified service has been marked for deletion".
If I exit the Uninstall sessions, and then reboot in order to try again, it just states "An incomplete installation was detected. Run setup to complete Exchange installation." It appears that all Exchange files are still on the server too, however, the server in question is no longer listed in the EAC under the "Servers" section.
Any ideas?
