How do you disable attachments in a list with items over 5000 items?
I have a list and it has over 5000 items, and when I go to the list settings, I go to turn attachments OFF (disable) I click OK and I get the error: The attempted operation is prohibited because it ...
I tried to "reproduce" the same behavior by creating a large list (5100 items) through script, in both modern and classic team site. But even there, I was able to disable attachments afterwards.
Did you try to handle the settings through PowerShell / CSOM?
A (maybe huge?) solution could be to create a second list using the "from an existing list" option, move items from the first list to the second using PowerShell / CSOM / Power Automate to be under 5000 items, disable list attachments and move back items.
