The article called "The System Attendant homeMDB attribute is missing" is here:
It's a refference from the Best practise analyzer which will tell if there's a server where the SA is missing a homemdb value.
But I havent found an article for Exchange2010, where the path to the databases are slightly different.
In Adsi Edit you should instead use this path:
- Configuration [
- CN=Microsoft Exchange
- CN=Administrative Groups
- CN=Exchange Administrative Group (
The new path is is obviously because the Storage groups are gone in Exchange 2010, and the databases are now global instead of dedicated to a server.
