Hi Bjorn Dirchsen,<br />
Please use this article to move mailboxes to another database.<br />
<a href="https://www.experts-exchange.com/articles/31741/Move-mailboxes-in-bulk-or-one-by-one-to-another-database-in-Exchange-2010-2013-2016.html?headerLink=workspace_article" rel="ugc">https://www.experts-exchange.com/articles/31741/Move-mailboxes-in-bulk-or-one-by-one-to-another-database-in-Exchange-2010-2013-2016.html?headerLink=workspace_article</a><br />
<br />
Use this command to see the databases and server<br />

<pre><code class="code-1 nolinks" id="code-20-42745019-1"><span>Get-MailboxDatabase | ft name,server</span>
</code></pre>
<br />
Use this to move all mailboxes to &nbsp;one database to another<br />

<pre><code class="code-1 nolinks" id="code-20-42745019-2"><span>Get-Mailbox -Database Mailboxdboldserver | New-MoveRequest - TargetDatabase Mailboxdbnewserver -BatchName &quot;Mailboxdboldtomailboxdbnew&quot;</span>
</code></pre>
</div>

@mas - thank you for the link. All mailboxes are in one Mailbox database - &quot;Mailbox Database Exchange 2013&quot; on EX1. So I don't understand what all the mailboxes are doing on EX2.<br />
<br />

<pre><code class="code-1 nolinks" id="code-20-42745039-1"><span>[PS] C:\&gt;Get-MailboxDatabase  -identity &quot;Mailbox Database Exchange 2013&quot;</span>
<span></span>
<span>Name                           Server          Recovery        ReplicationType</span>
<span>----                           ------          --------        ---------------</span>
<span>Mailbox Database Exchange 2013 EX1             False           None</span>

As commented by Akhater please remove copies<br />
This will remove all copies from EX2 and remove EX2 from DAG.<br />

<pre><code class="code-1 nolinks" id="code-20-42745132-1"><span>Get-MailboxDatabaseCopyStatus -Server EX2 | Remove-MailboxDatabaseCopy</span>
<span>Remove-DatabaseAvailabilityGroupServer -Identity ExDAG -MailboxServer EX2</span>
</code></pre>

Check my KB:<br />

I wrote this to recover failed server, however you can just follow steps for removing. It is for 2010, however most of the steps will be similar for 2013.

<div>
Ok. I'll give it a try in our test environment :) <br />
<br />
Thanks everyone for your help so far. I'll keep you posted with my findings.

Hmm. After removing both server Ex1 and EX2 from the DAG, Removing the DAG and uninstalling Exchange from EX2 (EX2 is stil a Domain member server, but no Exchange on it), i still see people on the EX2 when I issue the Get-Mailbox command.<br />
<br />

<pre><code class="code-1 nolinks" id="code-20-42745984-1"><span>Name          Alias   ServerName       ProhibitSendQuota</span>
<span>----          -----   ----------       -----------------</span>
<span>room1         room1   EX2	         Unlimited</span>
<span>room2         room2   EX2	         Unlimited</span>
<span>user1         user1   EX2	         Unlimited</span>
<span>user2         user2   EX2	         Unlimited</span>
</code></pre>
<br />
Funny, issuing the command:<br />
<br />
[PS] C:\Windows\system32&gt;get-ma<wbr />ilbox -server EX2 returns:<br />
<br />
Exchange server &quot;EX2&quot; was not found. Please make sure you typed...<br />
<br />
I'm at a loss here...
</div>


<div>
Wait for AD replication, also now your can remove Ex2 from AD.
</div>


<div>
Ok. Found the reason for the strange behaviour of the Get-mailbox command in this article:<br />
<br />
<a href="https://blogs.technet.microsoft.com/appssrv/2014/03/10/get-mailbox-does-not-reflect-the-correct-server-name-for-mailboxes-on-databases-for-a-dag/" rel="ugc">Get-Mailbox does not reflect the correct Server name for Mailboxes on databases for a DAG</a>
</div>


<div>
Ok. Final question regarding this server decommissionning:<br />
<br />
I'm not able to send e-mail (at all) from the OWA to any user in the organisation. The webmail says<br />
<a href="https://filedb.experts-exchange.com/incoming/2018/11_w48/1405538/Capture.JPG" target="_blank" title="Capture.JPG (13 KB)"><img alt="Capture.JPG" class="file-block lazyload" style="max-width: 330px;" data-src="https://filedb.experts-exchange.com/incoming/2018/11_w48/1405538/Capture.JPG" /></a><br />
This appeared after the removal of the EX2 server and DAG.<br />
<br />
Any clues?

Yes I told you to ignore the server in a dag ☺<br />
<br />
Regarding your other question, since it is not related to the original one and to be fair with all experts, please consider opening a new thread for it <br />
<br />
Thanks
</div>


<div>
Thanks everyone for the support. I've (almost) succesfully shut down the EX2 and the DAG. The server is operational, but with an (possible directly unrelated) issue with the OWA.<br />
<br />
Thanks, guys!
</div>


<div>
I advise you to recycle your Ex1 server during off hours and check it. Lot of time reboot fixes the issue.

Ok. We have a dual Exchange 2013 setup - EX1 and EX2 - in a DAG . Both servers has the Mailbox &amp;&nbsp;CAS roles<br />
I want to kill the DAG and only have one Exchangeserver being the server EX1.<br />
I've removed the mailbox databases from the EX2 server. But I still have a ton of mailboxes (58) that is on the EX2 server.<br />

[PS] C:\&gt;get-mailbox -server EX2 | sort-object name reveals:<br />

How do I move the mailboxes to the EX1 server?<br />
