I'm getting a similar problem to another poster, but with different error codes, so I created a new thread. I have no public folders, so stopped exchange services and moved the contents of the "second storage group" to another folder, then restarted exchange. The EMC offered to create new, empty database, but this also would not mount. Exchange is running using CCR on the mailbox server, with 2 hub/client accessservers using NLB, the only other thing that isn't working properly is forms based authentication. The database mounted successfully after Exchange was installed. --------------------------------------------------------Microsoft Exchange Error--------------------------------------------------------Failed to mount database 'Public Folder Database'. Public Folder DatabaseFailedError:Failed to mount (online) database 4ed58bcb-546c-469b-9e07-fa007ea84c1f. Reason: MapiExceptionADPropertyError: Unable to mount database. (hr=0x80004005, ec=2418) --------------------------------------------------------OK-------------------------------------------------------- Any suggestions? rob

Just to clarify what we've tried: setup /PrepareAD setup /PrepareLegacyPermissions restarting all exchange services restarting exchange services one member at a time I don't know if it's because the active cluster member won't mount the store, but there are no database or log files created on the passive member (I guess this could be expected until CCR is active on the store). the following have been logged: Event Type:ErrorEvent Source:MSExchangeISEvent Category:General Event ID:9519Date:09/01/2007Time:22:14:49User:N/AComputer:FRANKDescription:Error 0x972 starting database "Second Storage Group\4ed58bcb-546c-469b-9e07-fa007ea84c1f" on the Microsoft Exchange Information Store.

Sorry - forgot to mention - I manually stopped the cluster service on the active node, and attempted to mount the store on the other server, but got the same error. Trying to delete the public folder database gets this error: [PS] C:\>Remove-PublicFolderDatabase "MSx\Second Storage Group\Public Folder Database" -removelastallowed: $trueRemove-PublicFolderDatabase : The critical property 'PublicFolderHierarchy' ismissing in the PublicFolderDatabase object 'msx\Second Storage Group\Public Folder Database'.At line:1 char:28+ Remove-PublicFolderDatabase <<<< "MSx\Second Storage Group\Public Folder Database" -removelastallowed: $true rob

Rob I am getting the same errors in my event log too. the db mounted fine after the install then bam...I was hoping to migrate off of 03 this weekend but I dont see it happening now :( Ken

I was having this problem too. It started when I removed the Exchange 2003 First Adminstrative Group from Active Directory with adsiedit. The old EX2003 server was not in the Old Administrative Group, but Ex2007 public folders had a dependency on a"Folders Hierarchies"object in the old Administrative Group. The problem was resolved when I restored Active Directory form a SysState backup of the previous day. The missing object in AD that caused this is . . .(im my case) . . . CN=Services, Microsoft Exchange, Org5112, Administrative Groups, First Administrative Group, Folder Hierarchies, >> %deleted object% This fixed the problem, but I am trying to figure out if the Old Ex2003 Administrative Group must alway be there, or if their is a configuration command that would eliminated this dependency.

Hi, I've the same problem. Do I really have to restore my state? Or is there another solution? Thanx and regards, Jan Bosch

This may or may not be practical for you depending on how many mailboxes there are. . . I have about 15 mailboxes. I preferred to get rid of the legacy organizaton dependencies, so I exported all the mailboxes to .pst files, removed everything from Active Directory related to the legacy Exchange 2003 organization (with ADSIEdit) and ran a new clean install of Exchange 2007. That was two hours well spent.

Hi Jan! To avoid this, addnew exchange server account to old Exchange Domain Servers security group and old exchange server account to new Exchange Servers security group Restart. Enjoy. Best regards, Alex Nikiforov.
