We have Exchange 2007 and Exchange 2010 servers under the same organisation but admin by different subsidies. Each one only own one version and administrate by their own people. One day received report from Exchange 2007 administrator that he cannot modified distribution list. Error message is "You must use management console version 14.0.100.0 or late to modify this object." Suspected the cause is due to previous introduction of a testing Exchange 2010 server and use that EMC to edit that subject.
Is there any way to solve above problem ? Preferred that is one time effort. Is it possible to fall back its properties to allow it to be editable by Exchange 2007 EMC ? Unsure whether installation of EMC for Exchange 2010 can help and whether there is license issue ? Thanks in advance.
