This is a common problem in Exchange 2010 which I have seen multiple times so I have decided to blog it. When creating a new mailbox database, directly after mailbox creation you might receive the following error:
--------------------------------------------------------
Microsoft Exchange Error
--------------------------------------------------------
Failed to mount database 'Database2'.
Database2
Failed
Error:
Couldn't mount the database that you specified. Specified database: Database2; Error code: An Active Manager operation failed. Error The database action failed. Error: Operation failed with message: MapiExceptionNotFound: Unable to mount database. (hr=0x8004010f, ec=-2147221233)
. [Database: Database2, Server: ADM-EXCH-01.canning.wa.gov.au].
An Active Manager operation failed. Error The database action failed. Error: Operation failed with message: MapiExceptionNotFound: Unable to mount database. (hr=0x8004010f, ec=-2147221233)

![]()
This error can be caused when multiple domain controllers exist in the same Active Directory site. Microsoft Exchange creates an object in the configuration partition to represent the mailbox database. When Active Manager goes to mount the newly created database it may talk to a different domain controller in the same Active Directory site which does not yet contain the record for the mailbox database.
These databases objects in Active Directory are msExchPrivateMDB class objects and reside under:
Configuration Partition --> Services --> Microsoft Exchange --> Exchange Org Name --> Administrative Groups --> Exchange Administrative Group (FYDIBOHF23SPDLT) --> Databases
In the event you receive this error simply wait a few minutes for AD Replication to catch up and then attempt the database mount operation again.
