I’m getting a consistent 403 Forbidden when using Excel Online (Business) → List rows present in a table against an Excel file stored in OneDrive for Business (My files). The action fails while trying to load/resolve values (Location/File/Table) and/or at runtime with an error like “Error from token exchange: Permission denied due to missing connection ACL”. I created the flow myself (not shared, not in a shared run-only setup), I’m signed in with the correct work account, and I’ve already tried the usual fixes: recreating the Excel/OneDrive connections, deleting and re-adding the action, rebuilding the flow, testing in incognito/another browser, and confirming it still fails on normal Wi-Fi (so it’s not hotspot/network related). Despite all of this, Power Automate still returns the same 403 “missing connection ACL” token exchange error when attempting to access the OneDrive Excel file.
