I've been getting the following errors on my Exch2003 server for the lastfew of months now. Event 8197 is logged every 25mins and I've gone over Microsoft article 828764time & time againbut have been unable to relsove the issue. Event 9175 only appears when the offline address book is sheduled to built at 5am. Needless to say the offline address book has not been updated for a few months now. It's been very difficult to get information regaring these problems. Apart from that everything else appears to be working fine. Any advise would be a great help! Event ID 8197 - MSExchangeFBPublish Error initializing session for virtual machine SERVER. The error number is 0x80040111. Make sure Microsoft Exchange Store is running. MSExchangeFBPublish Event ID 9175 - MSExchangeSA The MAPI call 'OpenMsgStore' failed with the following error: The information store could not be opened. The logon to the Microsoft Exchange Server computer failed. MAPI 1.0 ID no: 80040111-0286-00000000 Kind Regards, Wee Dod

I've managed to fix the above issue.......thankfully. I found that there was a couple of duplicate 'ServicePrincipalNames' in AD.Eg....HOST/Servername. How these were created I have no idea. I found the error whilst reviewing the domain controllers event log (system). Event ID 11 appeared "see KB321044" which helped me find the duplicate entry. Once these were removed using ADSI Editthe above errors stopped and we can now build our "Offline address Book" once more. Hopefully this will assist other people. Regards, Wee Dod

Hi Dod, I've received this kind of Error message thousand times: 16:32:32 Microsoft Exchange offline address book 16:32:32 Not downloading Offline address book files. A server (URL) could not be located. 16:32:32 0X8004010F do you also have a problem in mounting secondary storage group database which contains Public Folder ? as I seems to get stuck in DELETING and mounting that Secondary DB.
