Over the weekend we upgraded our Exchange 2000 Standard installation to the Enterprise Edition. This morning, all seems to be working fine except for an error in the event log: -------------------------------------------------------------------- Source: MSExchangeSA Event ID: 9301 Failed to generate offline Address Book /dc=com/dc=xxxxxx/dc=INT/cn=Configuration/cn=Services/cn=Microsoft Exchange/cn=XXXXXXXX/ cn=Address Lists Container/cn=Offline Address Lists/cn=Default Offline Address List, error '80072030' -------------------------------------------------------------------- After fairly exhaustive research, I have come up with little or nothing on the error. Anyone have any idea? thanks, bret
