This tool collects various information and statistics about the email processing process and displays them graphically.
Here you can find instructions to check if the Exchange Server Toolbox might be the cause of the problem.
If you want to completely rule out the possibility that the Exchange Server Toolbox is responsible for problems, you can completely remove it from the email processing chain.
