What would be the best approach to share / divide responsibilities for managing exchange server in single forest.
CompanyA has taken over CompanyB and CompanyC. They migrated CompanyB and Company C into CompanyA's single forest. CompanyB and Company C will share the same SMTP namespace and will be loctaed in the same physical location which will be linked to back to CompanyA network. There will be no server at the location however there will be IT team that would like to admin the site.
What would be the best approach so IT team on site could fully manage the site?
