Error message can be found in BizTalk's Message Flow window

Sometimes it seems like BizTalk is trying to hide error messages. So, if you can't find any sufficient message neither at the suspended instances nor in the event viewer, here is another source of information:



1. Open the Message Flow using the instance's context menu of HAT or Administration Console
2. Use the link "Show tracked Orchestration Exceptions".

This will show you an error text, which actually explains the error. :-)
