Exchange 2013 DAG move OAB

I removed a member from a exchange 2013 DAG. Outlook is still connecting to it. When I run the test autoconfiguration it is using the old server for OAB. How do you move the OAB to a different server when in a DAG?

Going by these steps the OAB generation server isn't the server I removed. How do I get the autodiscover to not use the old server's URL for the OAB or anything else?

For a DAG environment, identifying OAB generation server(s) is a two-step process.

Step1: Identify the mailbox database hosting organization mailbox with OAB Gen capability.

Use the following command to list the arbitration mailboxes with persisted capability of OABGen and database on which this mailbox is hosted:

Get-Mailbox -Arbitration | where {$_.PersistedCapabilities -like "*oab*"} | ft name,database

Step2: Identify the mailbox server where the database hosting organization mailbox is mounted

Use following command to identify active copy of mailbox database:

Get-MailboxDatabaseCopyStatus db1

The server where database status is “mounted” is the current OAB generation server.

You could force the OAB generation which should update the OAB url

I tried that it still hasn't switched over, i'll see what happens over night.

But when I look at the arbitration mailboxes they are all pointed to the old server but are listed as being on the database that is in the DAG. Could that be causing the issue of still trying to use the old server and how could I get it switched so they are listed on the correct servers?

Also, if it makes a difference the server I am removing was the first exchange 2013 server.

If you want to stop Outlook from using that server for anything, just change all of the URLs on the server to point to the server you want them to use.
That includes Autodiscover, Web Services, OAB etc. See my list for Exchange 2010 (which is the same for Exchange 2013) here: http://semb.ee/hostnames

Instead of doing that can I just uninstall exchange and outlook will stop using it, like i'm planning on doing? Since outlook is still using that server I want to make sure everything is switched over from it before I uninstall so problems don't arise after its unisntalled.

You can just remove Exchange, however that could upset any clients that are currently using it until Autodiscover has kicked in. If you change the URLs in advance then all traffic is going to the other server.
