I have a managed property and I have been told that I need to delete it from the tenant level schema. Bit confused to what this means
Tenant level is your entire Office 365 "world"
That is the level above all your site collections.
To access the Tenant level managed properties go through:
- In the app launcher click "Admin" this will bring you to https://portal.office.com/admin/default.aspx
- In the left menu click "Admin | SharePoint" this will bring you to https://XXX-admin.sharepoint.com
- In the left menu click "Search"
- In the main content click "Manage Schema" this will bring you to https://XXX-admin.sharepoint.com/_layouts/15/searchadmin/ta_listmanagedproperties.aspx?level=tenant where you manage your tenant level managed properties
