Scenario:

You have installed an Exclaimer Outlook Add-in on a user’s computer and it is not shown in Microsoft Outlook, even after you have checked thoroughly:


  • There are no errors in the event logs
  • Microsoft .Net Framework 3.5.1 is installed
  • Visual Studio Tools for Office is installed
  • You have Outlook 2013 on Windows 8/8.1. When you close and reopen Outlook, the Add-In is still inactive.

This may apply to:


  • Email Alias Manager Outlook Add-In
  • Mail Archiver Outlook Add-In

Reason

An Exclaimer Add-In may be inactive is because the Windows Registry loadbehavior key is set to Unloaded at start-up.


Solution

To change the loadbehavior key, follow steps below.


Note: These instructions involve making a change to the Windows Registry. We strongly advise that you complete a backup of the registry before to following these steps. For further information about how to back up and restore the Windows Registry, see Microsoft KB Article 322756: How to back up and restore the registry in Windows , in the Microsoft Knowledge Base.
  1. Click Start and then Run.
  2. Enter regedit and click OK to open the Registry Editor.
  3. Expand the tree in the left-hand pane and navigate to the path below:

    The root path is always:
    HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins\
    Then go on to one of the following paths for your required product:

    Exclaimer Email Address Manager:
    HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins\Exclaimer.IdentityManager.Addin
    
    Exclaimer Mail Archiver:
    HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins\Exclaimer.MailArchiver.OutlookAddIn
    
  4. Change the DWORD loadbehavior to 3.
