Can't create a new send connector in Exchange Control Panel in Exchange Server 2013

Applies to: Exchange Server 2013 EnterpriseExchange Server 2013 Standard Edition


When you use Internet Explorer 11 to access the Exchange Control Panel (ECP) in a Microsoft Exchange Server 2013 environment, you can't successfully perform the following operations:
  • Create a new send connector or change the existing send connector
  • Add secondary SMTP address to a user mailbox


This issue occurs because the ECP pop-up window request isn't handled reliably by Internet Explorer.  


To fix this issue, install Cumulative Update 13 for Exchange Server 2013 or a later cumulative update for Exchange Server 2013.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
