Answer / Solution

To check if the Exchange Server Toolbox is the reason for emails not arriving, you can search for the email in the Event Viewer. To do this, you can filter by the email addresses or search for emails that were not delivered in the "Delivered" column. If the email is not listed or is marked as "Delivered", then Exchange Server Toolbox is not the reason the email was not delivered.
