MapiExceptionTooManyMountedDatabases – Unable to Mount Exchange 2013 Recovery Database


MapiExceptionTooManyMountedDatabases – Unable to Mount Exchange 2013 Recovery Database

While performing recovery of mailbox in Exchange 2013 Server you may come across the below error message after creating recovery database in Exchange Server 2013

The first error message will get disappeared if you wait for few seconds this is due to AD replication time limit

Error Message 1:

[PS] C:\>Mount-Database RDB05
Failed to mount database “RDB05”. Error: An Active Manager operation failed. Error: Couldn’t find the specified
mailbox database with GUID ‘3fbd735e-8971-4c35-ab41-7162ea4e16a6’. [Database: RDB05, Server: MBX01.MAIL.COM]
+ CategoryInfo          : InvalidOperation: (RDB05:ADObjectId) [Mount-Database], InvalidOperationException
+ FullyQualifiedErrorId : [Server=MBXV01,RequestId=2f1842f5-5291-4e81-b15c-8be44d51df15,TimeStamp=1/10/2014 6:2
6:49 AM] BF20CAA1,Microsoft.Exchange.Management.SystemConfigurationTasks.MountDatabase
+ PSComputerName        : MBX01.MAIL.COM

After few second started to get different error message 2 from the previous one as shown below. Thought the product has evaulation copy or not licensed. Verified on running the following command

Get-Exchangeserver -Identity MBX01 | fl *produ*, *valid*

The product is enterprise edition and it is activated already. But still it throw the error message and while verifying the database found there is already recovery database exist and it is mounted. Dismounted the older recovery database and started to mount the new recovery database in Exchange server 2013 and it started to work fine.

Error Message 2:

[PS] C:\>Mount-Database RDB05
Failed to mount database “RDB05”. Error: An Active Manager operation failed. Error: The database action failed. Error:
Operation failed with message: MapiExceptionTooManyMountedDatabases: Unable to mount database. (hr=0x8004060e,

Moral: In Exchange Server 2013 you can have only one recovery database mounted state and it doesn’t support more than one recovery database in the Exchange organization.
