<div>
That's Arbitration mailboxes and they can be moved to another database like all other mailboxes. &nbsp;Can you move it to another db then try deleting it?
</div>


<div>
will moving this cause any issue,and how do i move it?
</div>


<div>
It shouldn't cause any issue because you wanted to delete the original mailbox database and move the mailboxes. &nbsp;Here is an example on how to move it using Exchange PS.<br />
<br />
You can use the<b> New-MoveRequest </b>cmdlet<br />
<br />
<b>[PS] C:\&amp;gt;Get-Mailbox | Where ArchiveDatabase -eq &quot;Mailbox Database 2 | New-MoveRequest -ArchiveOnly -ArchiveTargetDatabase &quot;Mailbox Database 1&quot;</b>
