We have a pure Exchange 2007 implementation. We are trying to install Exchange 2007 in a CCR under Hyper-V. We have the Cluster defined.We have the Quorum share defined based upon the technet instructions. The net share with permissions have also been done per the instructions. We install the Active node with E2K7. The E2K7 server portion of the install fails with not being able to create and mount the Mailbox DB. The Event viewer indicate that it is possibly due to an AD permission problem in defining the Storage group path. I can access the Store and see the DB in the First Storage Group in Exchange Console, but the actual DB file is not created. I have tried to remove and re-create the mailbox DB. We get the following errors. Any help is appreciated. Doug Mount MalibuEXCLDB1 Failed Error: Exchange is unable to mount the database that you specified. Specified database: MalibuEXCL\First Storage Group\MalibuEXCLDB1; Error code: MapiExceptionCallFailed: Unable to mount database. (hr=0x80004005, ec=-1023) . Exchange Management Shell command attempted: mount-database -Identity 'CN=MalibuEXCLDB1,CN=First Storage Group,CN=InformationStore,CN=MalibuEXCL,CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=dd,DC=malibu,DC=com' Elapsed Time: 00:00:02

If your install fails during the installation regardless you will definitely have a problem. I suggest to uninstall e2k7 and reinstall it again.

Thanks for the response. Did that twice. Not sure what to to get the install to work. Doug

Hi Doug, Run below command and check the edb file path is correctly available and exists. Get-MailboxDatabase Database Name | FL Identity, EdbFilePath Additionally check below KB if it matches the event ids in your case. Event ID 9519 "Error 0x80004005" is logged in the Application log when you try to mount a database in Exchange Server 2007 http://support.microsoft.com/kb/925825 You may alsorun FileMon and try to mount the database and check the FileMon log for any access denied error while accessing file/folder by any account. FileMon for Windows v7.04 http://technet.microsoft.com/en-us/sysinternals/bb896642.aspx

Issue description: After create new database in the storage group, it cant be mounted on the CCR Possible cause: Permissions have not been applied properly Known resolution: a. Launch ADSIEditor, expand Configuration Container->CN=Configuration, DC= Domain_Name ,DC=com->CN=Services ->CN=Microsoft Exchange->CN= Your_Organization_Name b. Removed SELF from the Organization object all the way down to the store c. Check the issue, if the issue still persisted, go on d. Please try method 1 in the KB 925825 which Amit provided e. Check issue again Troubleshooting: 1. DB file still not generated currently, is it correct? 2. Run a health check on the server with ExBPA to look for more error info 3. Please reproduce the issue, is there any error info occurred in the application log 4. Whether the error info in the EMS same as in the EMC, if not, please post here for analysis Notes: Mount-database MalibuEXCLDB1 [We dont need to input full path of database as long as theres no other databases which use same name in the organization] 5. Please try to create a new storage group for testing

HI, Doug. How's the issue currently?

The issue was resolved by deleting and adding another DB.Sorry about the response delay.Doug
