i’m trying to connect to my Sharepoint through “Microsoft Graph Security OAuth2 API”. I want to download to an excel file so i can import data to mysql. But i can’t authorize. I’m using the “Microsoft Graph Security OAuth2 API” for several other applications such as an Plugin for WP or our virus scanner. This all works fine, but when i try to connect with th n8n credentials. I will always get an error.
"Client authentication failed (e.g., unknown client, no client authentication included, or unsupported authentication method).
what i did
I added the credentials and made the app registration on microsoft azure.
n8n version: 0.201.0
Database you’re using (default: SQLite): SQLite
- Running n8n with the execution process [own(default), main]:
Running n8n via [Docker, npm, n8n.cloud, desktop app]: npm
Hi @Frank_Loeffler, welcome to the community
I am sorry to hear you’re having trouble. I just gave this a go on my end with a newly registered app in the Azure portal and didn’t run into any trouble here with the authorization. My settings look very similar to yours:

Under 0.201.0 and 0.202.1 I was getting this message:
Now under 0.204.0 I’m getting this:
