An Exclaimer Outlook Add-In Is Inactive

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.

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.
