Solution:

get-mailboxdatabase 3
Disabling the isexcludedfromprovisioning
Get-mailboxdatabase | set-mailboxdatabase -isexcludedfromprovisioning $false
Verifying again on creating mailbox

get-mailboxdatabase 4
Worked Perfectly
What is the purpose of isexcludedfromprovisioning Parameter ?
Note from Technet : http://technet.microsoft.com/en-us/library/ff477621(v=exchg.150).aspx

The IsExcludedFromProvisioning parameter has have two valid values, $True and $False. When you set this property to $True, the mailbox database is excluded from the automatic distribution process. When you set it to $False, the mailbox database is included in the automatic distribution process. The default value is $False.
When a mailbox database is excluded from automatic distribution, the only way to create a mailbox in, or move a mailbox to, the database is to use the Database parameter on the New-Mailbox and Enable-Mailbox cmdlets or the TargetDatabase parameter on the New-MoveRequest cmdlet.

    Thanks Raji..I have a question…suppose I set isexcludefromprovisioning parameter to true for one database but that also prevents me moving mailboxes into that database…how can I achieve both…database should be excluded from provisioning and we can move mailboxes into this databse as well…any help
