If you ever need to get from a Notification subscription ID to the subscription name it is luckily quite easy to do.
First locate the following in the notification email Notification subscription ID generating this message: 02F7588F-3BEA-BE7A-A004-D4863FA1119D
Then use the following power shell command:
Get-SCOMNotificationSubscription -id <Notification ID > | ft DisplayName
and replace <Notification ID > with the Notification subscription ID, in this example 02F7588F-3BEA-BE7A-A004-D4863FA1119D
Get-SCOMNotificationSubscription -id 02F7588F-3BEA-BE7A-A004-D4863FA1119D | ft DisplayName
