Scheduled Refresh continues for Dataset in deleted Group Workspace

[Stewart1]

I had a Group Workspace with a dataset that I had scheduled to refresh. I deleted the group, but I am continuing to receive emails informing me the refresh has failed. How do I access the dataset to remove it, having deleted the group?

Update: I managed to get our Office 365 Admin to re-add me to the group - it wasn't deleted, I had simply removed my own membership of the group, even through I was still the group owner. However, even the restored group does not show the dataset that is failing. I've uploaded a new dataset with the same name - it doesn't fail, but I am still receiving failure notifications. How do I track down this failure and stop it?
