Hi,

The error message "invalid_request: The provided value for the input parameter 'redirect_uri' is not valid" typically occurs in OAuth 2.0 authentication flows. This error suggests that there might be an issue with the redirect URI provided during the OAuth 2.0 authorization process. For assistance in configuring OAuth integration with Outlook, you can refer to the Odoo Documentation available at: Odoo Outlook Integration Documentation.

Hope it helps
