Hi, When I try to add a mapping to RefinableString00, it tells me: "The settings could not be saved because of an internal error: Attempted to perform an unauthorized operation." I am working on SharePoint online.. how to fix this please ?
I encountered the same error a few days ago. Reported it to MS Support and they told me there might be a bug in SharepointOnline which causes the Managed Properties page to default to the incorrect level of site instead of sitecol
So avoid using this URL
And simply use this URL instead
I've seen this error several times when I tried to adjust a managed property on the site collection level, you should try it in the
SharePoint Admin Centre > Search > Schema.
Worked for me.
