SharePoint 2013: SiteMailbox in Outlook not sync’ing document libraries

We’re using SharePoint 2013 Site Mailboxes to store and share important mail messages with our project teams. We noticed, that sometimes these mailboxes include document libraries from that SharePoint site, sometimes they don’t. Now we found the problem: if you enable the document libraries to be shown in the quicklaunch navigation, their content gets sync’ed with outlook. If you turn that feature off, the doc libraries will disappear.

However, we chose to turn this feature on. Because we have alot of sites, i wrote a short powershell script to do that. Please note, that you should check your quicklaunch navigation panels for duplicate entries now.

$spWeb = Get-SPweb "https://your.site.com"

	foreach($subSite in $spWeb.Webs)
		{
			foreach($list in $subSite.Lists)
			{
			 	if($list.BaseType -eq "DocumentLibrary") {
						$list.OnQuickLaunch = $true
						$list.Update()
				}
			}
		}

Hope this helps!
