Hi
I have a exchange 2013 CU 12 environment in to which i am updating to exchange 2016 CU3. The E2016 mailbox roles have been installed correctly and the CAS function is working correctly. The problem I have is with setting up a new DAG for the new servers.
The commands to enable the DAG have run correctly but when looking at the settings in EAC I get the following error.
"Object reference not set to an instance of an object"
and no DAG settings are displayed. I am also unable to add databases to the DAG.
Looking around the net I have found that I need to move the arbitration mailboxes to the new exchange servers to resolve this issue. Which is were i hit my current problem.
I can find the mailboxes but they refuse to be moved and just queued to be processed. Looking deeper I find that although the mailboxes are located in a active mail store the server name attached to them no longer exists.
Name Database ServerName
SystemMailboxab85} mbx_store2 xxcxxxbrc003
FederatedEmail.4c1f mbx_store2 xxxxxxbrc003
SystemMailbox{ mbx_store2 xxxxxxbrc003
Migration.8f3e7716- mbx_store2 xxxxxxbrc003
SystemMailbox mbx_store1 xxxxxxbmc002
Server ending 003 is no longer valid, server ending in 002 is. Both databases exists in a DAG.
I am assuming here that the issue is with server 003 no longer being valid although they all refuse to move to a new store.
Anyone have any ideas how i can resolve this?
thank you in advance.
