Best Practices Analyzer for Exchange 2010 is showing error Admin Group Exchange Administrative Group (FYDIB0HF23SPDLT). Microsoft Exchange System Attendant 'homeDB' is missing.
It sends me to this article: http://technet.microsoft.com/en-us/library/dd535374(EXCHG.80).aspx
I performed MAPI connectivty test: test-mapiconnectivity -verbose. I see no errors there.
Also, I do not see ill-effects that are described in the article such as the inability to view free-busy information.
When I use ADSIEDT as described in the article, where it says to expand CN=Information store / CN=<StorageGroupName> there is nothing to expand beyond CN=Information Store, nor is there anything there.
The only I thing I can think of is I did delete the first database. However, not until after following another article that describes moving all mailboxes off first. (Exchange won't allow me to delete anyway if there are any mailboxes in the store)
Not sure if I even have a problem other than what is reported in the Best Practices Analyzer.
