error Exchange 2013 Mailbox role fails stating to upgrade the discovery mailboxes to R5 version

Posted on Updated on

I was doing installation of second Exchange Server 2013 Mailbox Role for my DAG (Production) today and got this error. This error reminded me my Microsoft Exchange PSS days.

I have seen this error before when exchange server 2010 was RTM.


After reading different articles, I was able to resolve this issue by performing the following steps:

  1. open up ADSIEDIT.msc
  2. Open the Default Naming Context
  3. Locate the Users container
  4. Go to the properties of a 2010 user acount and locate the value that is set in the homMDB attribute. Make a copy of the contents that are set in that attribute
  5. Locate the CN=DiscoveryMailbox Search and go to properties
  6. In the homeMDB attribute paste in the value that was copied from the regular 2010 user account
  7. Repeat step 6 for the following system mailbox CN=SystemMailbox{1f05a927-30df-4fe0-8a40-136e6d78e2d1}
  8. Repeat step 6 for the following system mailbox CN=SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}

After updating the homeMDB value for the Discovery and two System Mailboxes restart the Information Store.

and it works now Open-mouthed smile

Problem : Error when running Step 7 Mailbox Role:Transport Service


Solution : You can disable IPV6 via regedit

1.Open registry.exe

2.Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters \

3.Double-click DisabledComponents to change the DisabledComponents entry

Note : If the DisabledComponents entry is unavailable, you must create it. To do this, follow these steps:

  1. In the Edit menu, point to New, and then click DWORD (32-bit) Value.
  2. Type DisabledComponents, and then press ENTER.
  3. Double-click DisabledComponents.

4.Type any one of the following values in the Value data field to configure the IPv6 protocol to the desired state, and then click OK:

Type 0xffffffff to disable all IPv6 components except the IPv6 loopback interface. This value also configures

5.To use the DisabledComponents registry value to check whether IPv6 was disabled, run the following command at a Windows command prompt:

reg query HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters /v DisabledComponents

6.Restart computer and,try again to upgrade CU3.
