Remove a site mailbox

After setting up a site mailbox, you may decide that you don’t really need it. You can remove the Site Mailbox app, which essentially hides the mailbox from those who are using the site.

Important: The site mailbox feature in SharePoint is being deprecated beginning in March, 2017. This feature will be removed entirely in a future release. New SharePoint organizations no longer have access to the site mailbox feature. Existing SharePoint organizations can no longer create new site mailboxes. Any site mailbox that was set up and deployed before March, 2017 will continue to function.

We will provide a process to help transition your existing site mailbox sites to an Microsoft 365 Group in September, 2017. If you currently use the site mailbox feature in SharePoint, you should consider changing to Microsoft 365 Groups instead to support your email collaborative scenarios. For more information, see Use Office 365 Groups instead of Site Mailboxes.

Note: The site mailbox feature will remain supported, but deprecated in SharePoint Server 2019, SharePoint Server 2016, SharePoint 2013 and SharePoint 2010 products. Customers are recommended to explore shared mailboxes as an alternative to site mailboxes.

  1. Click Settings Settings: update your profile, install software and connect it to the cloud > Site contents.

  2. Under Lists, Libraries, and other Apps, point to Site Mailbox, and then click ... for more information.

    Site Mailbox app, with ... button for more information.

  3. Click Remove on the box that pops up.

    Remove a site mailbox.

  4. Click OK to remove the site mailbox app.

Note:  If you remove a mailbox from a site, it won’t be displayed on the site, but it will still be visible in Outlook (if you’re using Exchange).

What else do I need to know?

There are a couple of things worth noting about removing a site mailbox:

  • The only way to fully delete a site mailbox is to delete the entire site itself. When a site is closed or deleted (either manually, or by following site closure policies), the site mailbox is also closed or deleted.

  • After removing the site mailbox app from a site, mail sent to the mailbox will still be stored. If you add the mailbox back to the site later, any mail sent to the site mailbox since it was originally created will still be there.
