Discovery mailbox can't be found

"The discovery mailbox, a hidden default mailbox that is required to search mailboxes, can’t be found. It may have been inadvertently deleted. This mailbox must be re-created before you can search mailboxes.”

If you are getting the above error when trying to run Audit reports from ECP such as Run a non-owner mailbox report try the following suggestions.

1. If the mailbox SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9} has not been deleted and is still in the users OU try enabling it by running the powershell command.  This is all I had to do to get it working. After I did my Exchagne 2007 to Exchange 2010 Migration.

Enable-Mailbox  -Identity "SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}" -Arbitration

2. If Discovery System Mailbox has been deleted then you will need to recreate it (Will not stop mail flow and will require no downtime)
  • Make sure the Mailbox SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9} is not present if it is you can delete it.
  • Install the Exchange media into a Domain Controller and run Setup /PrepareAD
  • Enable the mailbox using EMC - Enable-Mailbox -Identity "SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}" -Arbitration
This should solve your issue.

    Hi, when I run the command get this error:

    This task does not support recipients of this type. The specified recipient domain.local/Users/DiscoverySearch
    Mailbox {D919BA05-46A6-415f-80AD-7E09334BB852} is of type UserMailbox. Please make sure that this recipient matches the
    required recipient type for this task.

    on my exchange management console it appear the mailbox "Discovery Search Mailbox"

    I have multidomains, on what domain this account must be create on my root domain or in my resources domain?
