STATUS ====== Microsoft has confirmed this to be a problem in the Microsoft Exchange version 4.0 16-bit Windows client. MORE INFORMATION ================ The error message occurs because of the action that selecting the Delivery tab employs. "Delivery" is trying to log on while a logon mutex is held. A mutex is a type of lock that prohibits other threads from attempting to execute the same process. In the reverse case, the logon is completed before you attempt to do a second logon so no error is generated.
