I have an existing EV11 installation with a 4-server Exchange 2013 DAG. We have expanded the DAG to 8-servers and I'm in the process of setting up EV archiving to the new servers. Do I need to set-up a "local" database to hold the EV-system-mailbox (that does not failover with the DAG), or do I just use the active database on the active DAG members.? Please advise

Hi Alfred,
EV targets Exchange, not DAG (Unfortunately).
In your situation, you have 2 options. The one option mentioned (a local database on each server, not in the DAG, holding only the EV System mailbox).
The other options is to failover a dag holding a EV system mailbox to a new Exchange server, configure the task (using the EV system mailbox), then fail the database back. (described in the admin guide I believe)
I believe however it is the best option to have a local database, so the systemmailbox is (almost) always on the Exchange server the tasks targets.

Yes, you should have a local database on each Exchange server to hold the EV system mailbox.
