Hello, I even managed to connect my n8n to Google Calendar, but when trying to connect it to Excel, I received the following message:

Error: Insufficient parameters for OAuth2 callback.
More details
Received following query parameters: {}
Failed to connect. The window can be closed now.

My n8n setup:
n8n version: 1.84.3
Database (default: SQLite): SQLite
n8n EXECUTIONS_PROCESS setting (default: own, main): own
Running n8n via (Docker, npm, n8n cloud, desktop app): docker
Operating system: Ubuntu 24.04

Were there any permissions to grant (checkboxes) on the authorization popup page?

You might need to add scopes to your Microsoft App. See this

Files.Read and/or Files.ReadWrite is/are required for Excel - See this.
