Recently I came across unpleasant bugs in the Exchange Admin Center of Exchange 2016 CU2
Creating a custom Frontend receive connector for relaying purposes.
Normally I create these type of connectors with PowerShell, no problems there.
When I recently wanted to create this connector with the GUI, it showed me the screen below.
The option to select the Frontend Transport is Disabled
In the previous CU version, the screen shows like this.
Here you can select the Frontend Transport option
Of course you can create the connector with PowerShell: (example)
New-ReceiveConnector -Name ‘Relay connector’ -RemoteIPRanges @(‘10.3.2.22-10.3.2.40’) -Bindings @(‘0.0.0.0:25’) -Usage ‘Custom’ -Server ‘Server.domain’ -TransportRole ‘FrontendTransport’
Configure external access domain
Running Exchange Server CU 2 has another bug.
When you want to fill in the external domain to autofill all the external URL’s there is no way to select a server from the dialogbox (No server is shown)
In CU1 you can select the server!
Of Course there are several ways to do this with Powershell!
TechNet has a good script to perform this. : https://gallery.technet.microsoft.com/office/Exchange-Server-Client-510ad60b
