Exchange 2010 returns error "Load balancing failed to find a valid mailbox database" when creating mailbox RRS feed

  • Question

  • I have Exchange 2010 SP2 RU4 installed.

    When I use the PowerShell to execute the cmdlet: Enable-Mailbox

    It returns error "Load balancing failed to find a valid mailbox database". However, if I specify the -Database parameter, then it works fine.

    I've done some research on this error and have done the following verifications:

    1. Mailbox database is mounted 
    2. Exchange Mailbox role is installed
    3. Mailbox database is not excluded from the automatic mailbox distribution. Using cmdlet: Get-MailboxDatabase | fl isexcludedfromprovisioning,issuspendedfromprovisioning

    returns :

    IsExcludedFromProvisioning                   : False
    IsSuspendedFromProvisioning                  : False

    4. Mailbox database and the Active Directory are on the same site.

    Please help. I have no idea what is causing the error. Will updating to the latest SP2 RU 6 help to fix this problem?

    Please advice. Thanks in advance.
