SCOM 2012 R2 Error The connector the module is configured for no longer exists

Question

Hi All,
The Microsoft Operations Manager Connector Framework Alert Forwarding module failed to mark an alert for forwarding because the connector the module is configured for no longer exists. 
Connector Id: 57a14deb-a74b-520e-ac32-ba8d340d112d

Hi Mark,
You can try the following steps, 
This is because we have deleted a connector that still had a live subscription associated with it.  We need to go and delete that subscription to clean this up.  The problem is – the connector is gone, so the subscription is no longer available
in the UI.
Therefore – we will have to delete it manually.  This subscription (as all subscriptions) is kept in the “Notifications Internal Library” MP.  You need to export that MP to XML.  FIRST MAKE A BACKUP COPY OF THIS FILE IN CASE YOU MESS UP, then
open it for editing in Notepad, or your XML editor of choice.
All subscriptions in this MP are kept in the <Monitoring> <Rules> section.  To identify which connector subscription RULE is causing the problem – you can search for the connector ID, from the event 11502 above.  In my example – my connector
ID from this event is:  b7a64deb-f7ff-440e-bc30-d08d340dfe8d.
So – I search the XML for that string – and find b7a64deb-f7ff-440e-bc30-d08d340dfe8d in the <WriteActions> section of a specific <Rule>:
<WriteActions> 
  <WriteAction ID="WA" TypeID="SystemCenter!Microsoft.SystemCenter.ConnectorFrameworkAlertWriteAction"> 
    <ConnectorId>{b7a64deb-f7ff-440e-bc30-d08d340dfe8d}</ConnectorId> 
  </WriteAction> 
</WriteActions>
Good – I have identified the problem.  Now – I need to do two things:
Find the rule ID – to identify the display string associated with it… then delete that display string.
Delete the orphaned subscription rule.
So – I move up in the XML section of this rule – and I find my Rule ID.  (here is mine:)
<Rule ID="ProductConnectorSubscription2850f8e3_afe7_4c36_84d2_ee258bd086eb"
I then search for the part above which I bolded in blue (yours will be different – search for your string)
What this finds – is the display string section of the XML – which maps this GUID ID to the common name that you gave the subscription.  (here is mine:)
<DisplayString ElementID="ProductConnectorSubscription2850f8e3_afe7_4c36_84d2_ee258bd086eb"> 
  <Name>Process All New Alerts</Name> 
</DisplayString>
So – I need to DELETE this section from the XML…. just the section above, from my very specific <DisplayString ElementID="ProductConnectorSubscription2850f8e3<GUID> line, to the very next </DisplayString>.
Next – I need to delete the entire <rule> which contains the subscription we want to remove.  Mine will be from:
<Rule ID="ProductConnectorSubscription<GUID> line to the very next </Rule>
When you are happy – you can import this XML MP back into the management group.  It should import with no errors.  If you get an error – you made a mistake when editing the XML.  You can look on the RMS event log for the specific problem – there
will be a critical event there if it fails to import.
