Dear All Exchange experts,I'd like to mount my secondary database which contains Offline Address Book and the Public folder, but It keeps displaying this error Message:--------------------------------------------------------Microsoft Exchange Error--------------------------------------------------------Failed to mount database 'Public Folder Database'.Public Folder DatabaseFailedError:Exchange is unable to mount the database that you specified. Specified database: MCLAREN\Second Storage Group\Public Folder Database; Error code: MapiExceptionCallFailed: Unable to mount database. (hr=0x80004005, ec=-550).--------------------------------------------------------OK--------------------------------------------------------lately I found the Way to avoid this error from KBalert (http://kbalertz.com/925825/Event-logged-Application-mount-database-Exchange-Server.aspx)and I found out that the Exchange Servers entry has already filled and I still got the error message.I created another new Second database and I tried to delete the problematic database by right click on the file and click Remove, I got this error instead:--------------------------------------------------------Microsoft Exchange Error--------------------------------------------------------The public folder database 'Public Folder Database' cannot be deleted.Public Folder DatabaseFailedError:The public folder database "MCLAREN\Second Storage Group\Public Folder Database" contains the following offline address book(s):\Default Offline Address Book. Before deleting the public folder database, move the offline address book(s) to a web-based distribution point.--------------------------------------------------------OK--------------------------------------------------------how I'm supposed to get rid of this error message and make the Public folder up again ?any kinds of help would be much appreciated.Thanks
