In short, there are times when Exchange needs to stuff data away for one reason or another and it makes sense to use a mailbox for this purpose. After all, mailboxes go in databases and can be protected by high availability, and so on&hellip;</p> <p style="font-size: 13px; line-height: 20px;">The full set of arbitration mailboxes is exposed in all its glory by running the command:</p></div> <div class="og_rss_groups"><ul class="links"><li class="og_links first last"><a href="/blog/tony-redmonds-exchange-unwashed-0">Tony Redmond&#039;s Exchange Unwashed</a></li> </ul></div><p><a href="http://windowsitpro.com/blog/cherish-your-arbitration-mailboxes-just-case" target="_blank">read more</a></p> http://windowsitpro.com/blog/cherish-your-arbitration-mailboxes-just-case#comments Exchange Server 2013 Exchange Server 2016 Exchange Server 2010 arbitration mailboxes arbitration mailboxes Exchange 2010 Exchange 2010 Exchange 2013 Exchange 2013 Get-Mailbox Get-Mailbox mailbox migration service mailbox migration service mailbox moves mailbox moves Mailbox Replication service MRS MRS Replication service Tony Redmond&#039;s Exchange Unwashed Blog Tony Redmond&#039;s Exchange Unwashed Thu, 21 Apr 2016 12:00:00 +0000 89661 at http://windowsitpro.com Recycled email addresses and Outlook nicknames http://windowsitpro.com/blog/recycled-email-addresses-and-outlook-nicknames <div class="node-body blog-body"><p> The revelations (last October) that <a href="http://www.pcworld.com/article/2052586/microsoft-is-quietly-recycling-outlook-email-accounts.html" target="_blank">Microsoft is quietly recycling email addresses</a> from its Hotmail, Live, and Outlook.com domains might have come as a surprise to some.

It&#39;s a feature that has been around since Exchange 2000. Instead of the hidden view used by older versions, Exchange 2010 and Exchange 2013 implement a folder structure under the Recoverable Items root. It&#39;s more complicated because it has to support more than simple deletions. A separate quota is assigned to control the amount of space the Recoverable Items structure can occupy.
