Sharing Add-In Is Not Available


In some cases Outlook may disable the Zimbra Sharing Add-In. The Sharing Add-In is what enables you to share folders with others and access the contents other users have shared with you. If Outlook disabled the Sharing Add-In, you must manually enable it.


You don't see the sharing tab in the folder properties dialog


You don't see the 'Other Users Mailbox' in the 'File'->'Open' menu



Find the ZCO version

Navigate to Start -> Control Panel -> Add or Remove Programs, select "ZCS Connector for Outlook", and click the "Click here for support information" link. That will display the ZCO version.

Verify that the Sharing AddIn is not disabled

 * Navigate to Help->About->Disabled Items
 * If Zimbra Sharing AddIn appears, select it and click the Enable button
  • If you are using version 4.0.273 or newer, also
 * Find the following registry key and set its value to 3
 * HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\SharingAddin.Addin\LoadBehavior

Verify the Zimbra Client Extension is enabled

  • Navigate to Tools->Options->Other->Advanced Options->AddIn Manager
  • Verify Zimbra Client Extension is Enabled
