Hi,

we are running Exchange 2010 Enterprise and we do have an issue for several of our storages groups when we try to create the replication between our DAG. We get the the error ID 5000 :
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.

I've tried running this command but doesn't work at all:
[PS] C:\Windows\system32>Enable-Mailbox -Identity "SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}" -Arbitration
This task does not support recipients of this type. The specified recipient domain.lan/Users/SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9} is of type UserMailbox. Please make sure that this recipient matches the required recipient type
 for this task.
    + CategoryInfo          : InvalidArgument: (domain.lan/Users/S...8e6c29d823ed9}:RecipientIdParameter) [Enable-Mailbox], RecipientTaskException
    + FullyQualifiedErrorId : 12BC223B,Microsoft.Exchange.Management.RecipientTasks.EnableMailbox


Any suggestions to fix this please? For info, 2 datastores worked fine, the 6 others didn't.
Regards,
Dave

Hi,

I've run that and now it's even worst, I get this :
[PS] C:\Windows\system32>Get-Mailbox "SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}"
The operation couldn't be performed because object 'SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}' couldn't be found on 'server.domain.lan'.
    + CategoryInfo          : NotSpecified: (:) [Get-Mailbox], ManagementObjectNotFoundException
    + FullyQualifiedErrorId : 3CBAA9FE,Microsoft.Exchange.Management.RecipientTasks.GetMailbox

[PS] C:\Windows\system32>


The funny thing is that I can see it on the AD the famous user mailbox.
Any ideas?
David

Did you do:

Enable-Mailbox "SystemMailbox{guid}" -Arbitration

Open in new window


After that?

Hi,
In fact, even without this manipulation, now the replication works fine again. Thanks for the trick.
