EXCHANGE HUB/CAS CONNECTORS

try

$rc = get-ReceiveConnector -Name 'Wintel'
$rc.RemoteIPRanges += '121.12.23.12'
set-ReceiveConnector -Name 'Wintel' -RemoteIPRanges $rc.RemoteIPRanges

New-ReceiveConnector -Name Wintel -Usage Custom -Bindings '0.0.0.0:25' -RemoteIPRanges 192.168.8.1-192.168.8.100,192.168.8.101-192.168.8.103 (like that for example) -PermissionGroups 'AnonymousUsers'

@Akhater, sorry for my ignorance but how do you use the cmd? do you have to save it as pl file? or is it a vb?

no just the same way you ran the New-ReceiveConnector -Name 'Wintel' -Server 'hubcas.contoso.com' -Usage 'Custom' -Bindings '0.0.0.0:25' -RemoteIPRanges '121.12.23.12' -PermissionGroups 'AnonymousUsers'

run them one after the other

Exchange Management Shell - they're basically PowerShell commands but with the Exchange commands wrapped up (be aware that just running PowerShell won't be enough - has to be the EMS, hence why I mentioned it).

@Akhater - i have this error:
[PS] C:\Users\myName\Desktop>$rc = get-ReceiveConnector -Name 'wintel
Get-ReceiveConnector : A parameter cannot be found that matches parameter name 'Name'.
At line:1 char:33
+ $rc = get-ReceiveConnector -Name  <<<< 'wintel'

remove -name
 i

ii am assuming you already have a receive connector called wintel right ?

$rc = get-ReceiveConnector 'Wintel'
$rc.RemoteIPRanges += '121.12.23.12'
set-ReceiveConnector -Name 'Wintel' -RemoteIPRanges $rc.RemoteIPRanges

Yes i already have an existing with 50 IPs.
now i have this:

[PS] C:\Users\myName\Desktop>$rc = get-ReceiveConnector 'wintel' $rc.RemoteIPRanges += '121.12.23.12' set-ReceiveConnector -Name 'wintel' -RemoteIPRanges $rc.RemoteIPRanges
Get-ReceiveConnector : A parameter cannot be found that matches argument '$null'.
At line:1 char:27
+ $rc = get-ReceiveConnector  <<<< 'wintel' $rc.RemoteIPRanges += '121.12.23.12' set-ReceiveConnector -Name 'wintel' -RemoteIPRanges $r
c.RemoteIPRanges

wait each command on its own like

sorry didn't get you? you meant line by line?

$rc = get-ReceiveConnector 'Wintel' [enter]

$rc.RemoteIPRanges += '121.12.23.12' [enter]

set-ReceiveConnector -Name 'Wintel' -RemoteIPRanges $rc.RemoteIPRanges [enter]

the second i have this
[PS] C:\Users\myName\Desktop>$rc.RemoteIPRanges += '121.12.23.12'
Property 'RemoteIPRanges' cannot be found on this object; make sure it exists and is settable.
At line:1 char:5
+ $rc.R <<<< emoteIPRanges += '121.12.23.12'

Although Akhater's method is fully functionel =]

You can also use:
set-ReceiveConnector -Identity Wintel -Bindings 10.10.10.1:25 -RemoteIPRanges 192.168.8.1-192.168.8.100,192.168.8.101-192.168.8.102 (just by including the current ip range and add a comma and type in the second ip ranges that you want to add to the connector)

$rc.RemoteIPRanges

alone

I just tried it here and it is working

yeah sorry the first and 2nd works :)) the third line i have this:

[PS] C:\Users\myName\Desktop>set-ReceiveConnector -Name 'wintel' -RemoteIPRanges $rc.RemoteIPRanges

cmdlet set-ReceiveConnector at command pipeline position 1
Supply values for the following parameters:
Identity:

after "Identity:" i have the cursor blinking like its waiting for me to put something. thanks for your patience on me Akhater :}}

Genius!!!! The Guru The MAAAAN!!!

Akhater :) sorry to disturb again. do you know if possible to add "-Server" on that script? just to avoid loging in to every server? so i can do it on 1 HUB and just change the "-Server" entry?  if you have time :)  --  your script work well... it saved me a lot of time!!!!!
