I had an issue with an environment with a mixture of Exchange 2010 and Exchange 2016 servers. All mail to one of the Exchange 2010 servers was getting stuck in queue and not delivered.
This is a very weird error and I have not come across it in my many years working with Microsoft Exchange.
To fix this issue, the following two lines need to be added to the ExchangeTransport.exe.config file in the Exchange bin directory.
Then restart the Exchange Transport service. Mail flow should begin working again. For more information about this error please refer to the following Microsoft blog post:
