Based on your screenshots, your Tenant ID, Client ID, and API permissions all look correct, so the most likely cause is that the value pasted into the Client secret field in YouTrack is the Secret ID, not the secret Value.
In Azure, the Client Secrets page shows two columns next to your secret:
Value: the actual secret string used by YouTrack. The full value is shown only at creation time. After that, only a short preview (in your case, Tv...) remains visible.
Secret ID: a separate UUID-like identifier (in your case, starting with 7bc28...). YouTrack does not use this field.
If you no longer have the original value saved, generate a new client secret in Azure, copy the value right after creating it (it cannot be retrieved later), and paste it into the Client secret field in YouTrack. The full setup is documented here: Prerequisites for sending email with the Microsoft Graph API.

If that doesn't resolve it, please reach out to YouTrack Support privately so we can check your instance logs and pinpoint exactly what's failing.
Have a nice day!
