Administrators can delete any users scheduled reports. This can be useful if the user is unavailable to remove the scheduled report themselves, for example if they have left the organization.
If you are a JIRA administrator you can remove other users scheduled reports by following these steps:
Navigate to the Intelligent Reports Scheduled Reports page from the top JIRA menu.
Click the All Users Scheduled Reports button.
Click the Delete link next to the report you want to delete.
A pop up window will ask you to confirm your choice. Click OK to cancel the scheduled report. Note that cancelling a scheduled report does not delete the report template.
