Hi All,

I'm having problems with SCCM 2012 R2 and the Exchange Connector. My predecessor had originally set this up with one of our Exchange servers but since I have rebuilt the Primary server and it has a new Site code and the record of the old Primary server seems to still present on the exchange server. 

Easdis.log is showing the following error

ERROR: Exchange Organization [CN=NCGRP,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=******,DC=co,DC=uk] for [http://se********.******.co.uk/powershell] has already been configured on Site [P**] as [http://SE*******.******.CO.UK/powershell] with credential [].

Can anyone tell me where to find the SCCM config on the exchange server so I can change the site code? or if you think the error might be something else then let me know? 

Thanks :)

There's nothing stored on the Exchange server as far as I know. Everything is configured in ConfigMgr. You just have to grant permissions in CM12.

The exchange server has full permissions as does the exchange connector account. But for some reason it's remembering the old primary and I don't know how to change that.
