This is something that has been going on for quit some time now.
Is there something we can look for to find more details?
We get the following message:
Failed to send notification. Cannot find item with id 361 in list 'ListName'. Check the user has at least read permissions. Current user: xyz
The permissions for that list are all correct.
Maybe this might help.
We also have the same message for workflos where no action is taken for a week.
