<div>
Are the permissions on Autodiscover/RPC/RPC with Cert in IIS configured correctly? &nbsp;Also, is Outlook Anywhere configured and enabled on the 2nd CAS?
</div>


<div>
1) not sure how to check &quot;permissions on Autodiscover/RPC/RPC with Cert in IIS&quot;.<br />
2) why would Outlook Anywhere matter? &nbsp;I don't have it enabled on my 1st CAS.
</div>


<div>
you can only access a mailbox using a cas server in the same ad site as the mailbox server<br />
<br />
run the following cmdlet and post the result<br />
Get-MailboxDatabase | fl Name,RpcClientAccessServer<wbr /> <br />
<br />
Each database should have a FQDN value for the CAS or CAS array associated with its site<br />

</div>


<div>
The mailbox in site 2 wants to access the CAS in Site 1 (and does so successfully). &nbsp;I want the mailbox in site 2 to access CAS in site 2. &nbsp;
</div>


<div>
you need to look at the value from the command given earlier<br />
outlook always connects thru a cas server, and the RpcClientAccessServer value for the database determines which cas server the client uses
</div>


<div>
it comes back with CAS1 (site 1) as my CAS server for both of my databases. &nbsp;How do I assign a CAS to a particular site/database? (I'll be this happened because I created the database in site 1 originally and moved it to site 2)
</div>

I have 2 sites and both sites have seperate virtual servers running CAS, HT and MB roles.<br />
The 2nd CAS server is not working. &nbsp;It will allow you to access OWA but will not allow Outlook to connect. &nbsp;My goal is to allow the users at 2nd site use the 2nd CAS server.<br />
I have setup a DAG and trying to get redundency working. &nbsp;<br />
All services are running. &nbsp;I installed all the updates and sp1. &nbsp;All firewalls off.<br />
