Waiting time is dependent upon the amount of time Domain controllers take to replicate the database object.įollowing steps are performed at Exchange level: C:\>Mount-Database Test C:\>Get-MailboxDatabase Test -Status | fl name,*mounted* Name : Test MountedOnServer: Mounted : TrueĪnd same problem persists even after using the ECP utility. This issue can be resolved after waiting for some time but how long an Exchange Administrator has to wait is not specified. Information store process returns with an error from Information store Process to Replication Service and subsequently to Administrative endpoint- the point at which the mount was issued. As we check the flow, Replication service recognizes the presence of database but Information Store Process is not aware.Replication Service notifies the Information store Process to perform the mount.Command > goes to Primary Active Manager > passed to Replication Service of the node which owns the active mailbox database copy.In case of DAG, the issued command route is as follows: The issue arises when a new mailbox database is created and mounted immediately.Įxchange Administrators issues a mount command which is immediately referred to the Active Manager Process on the server. The process of creation of new mailbox database entry is as follows: When Administrators create a new mailbox database, it also creates an entry in the Database Configuration Container within the Active directory and this replicates to all domain controllers. Note: Exchange 2007 and earlier versions used Information store Process for creation and mount/dismount. This process runs within the Exchange Replication Service. Active Manager works with Information store to execute these requests. Active Manager Process is assigned the role of creation of mailbox databases and perform mount/dismount operations. Every server whether standalone or a member of DAG (Database availability Group) have an Active Manager Process. The evolution to Exchange 2010 and higher witnessed a new entity “Active Manager Process”. Earlier versions like Exchange 2007 consisted of “The Information Store” process was solely responsible for creating New Mailbox Databases and performing “mount and dismount” operations.
The process of mounting the database has changed for Exchange 2010 and Exchange 2013. Error: Operation failed with message: MapiExceptionNotFound: Unable to mount database.
Specified database: DBNAME Error code: An Active Manager operation failed.
Specified database: HU-DB Error code: An Active Manager operation fail”Įrror message is listed in detail in the box below:ĭBNAME Failed Error: Couldn’t mount the database that you specified.
“Couldn’t mount the database that you specified. The most common error encountered by Administrators is “Mailbox role Failed” and following message displays on screen: Installation steps for Exchange 2013 differ from Exchange 2007, however, once started the installation of Exchange 2013 server is relatively easy but the next process of mounting a new mailbox database on the server proved to be futile effort. As an Exchange Administrator, you own the responsibility of Exchange setup, resolution of problems and also Exchange migration. Exchange 2007 was outdated and hence posing a problem.
