This docs article shows how to delete dashboards, but only if the user has access.
https://docs.dataminer.services/dataminer/Functions/Dashboards_and_Low_Code_Apps/Dashboards_app/Creating_and_configuring_dashboards/Deleting_a_dashboard.html
We have a number of redudnant dashboards where we have no idea who the editor is, but need to delete.
How can we delete old dashboards where nobody has edit access?
example where there is no edit or delete right click option.

Hi Sam,
If you have access to the system itself, you can remove the dashboards from C:/Skyline DataMiner/dashboards. Note that this has some caching, so you might have to reload the webpage or restart IIS to see the effect.
You will have to do the manual edits on all DMAs
Can confirm this was successful deleting the dashboard files from our 16 dma servers.
I have submitted a pull request to update dataminer docs for this scenario
https://github.com/SkylineCommunications/dataminer-docs/pull/6991
Didn't need to reload IIS / Web, when I accessed dashboards after deleting from all dma, the orphaned dashboards were gone.
Thanks Wout,
On a DMS with 8 dma failover pairs, which dma would I logon to delete from the server?
