My Mailock Outlook add-in keeps disabling itself

Mailock for Outlook desktop intermittently disabled? Learn more...

Why does this happen?


Microsoft has some security measures in place to prevent slow add-ins from running inside Outlook. However, in many cases, add-ins without fault are being mistakenly marked as slow and disabled by Outlook. If this is not immediately corrected, Outlook may permanently disable them with no way to re-enable them via the user interface.


What can I do about it?


Please run through the following steps to fix this issue:


Force Outlook to always enable the add-in:


By default, the Mailock add-in installs with parameters that force Outlook to ‘Always enable this add-in’.


You can check this setting and reset it if necessary.


On the File tab, click 'Manage COM Add-ins' under 'Slow and Disabled COM Add-ins'.


You'll see a list of add-ins. Locate the Beyond Encryption entry and click 'Always enable this add-in', as shown in the image below, and select 'Apply'





You should then see a screen like the one below, select the 'Do not monitor this add-in for the next 30 days' and 'Close'.




In the event you see a slightly different screen, like the one below to advise the add-in has been disabled,  click here to run through the steps to enable the add-in again.




Changing the Load Behaviour:


On the Outlook 'File' tab, click 'Options', 'Add-ins' and with the ‘Manage:’ selection set to ‘COM Add-ins' at the bottom of the page, click the ‘Go…’ button and select the Beyond Encryption add-in from the resulting list.


You will be able to see the current load behaviour of the Mailock add-in, which should be set to 'Load at Startup' like this:



If the Load Behaviour displays differently, then it may be due to the registry setting that controls how the Mailock add-in is loaded. Please check with your local administrator/IT Team to follow the steps below.


Caution: When editing the Registry Editor, only amend the recommended steps below, amending other areas of the Registry Editor could have a serious impact on other applications on your computer.


Open your Registry Editor. To do this, open your Windows Start menu and type 'regedit'.


Go to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins\Beyond Encryption


Note what the LoadBehavior is set to. It will be a number like 0 or 1 or 3.


If the LoadBehavior key is anything other than "3" then follow these steps:


  1. Close Outlook (and all other Office programs to be sure). Make sure the "OUTLOOK.EXE" process is not running in the Windows Task Manager
  2. Open the registry editor again. Double-click the registry key to edit it.
  3. Change the Load Behavior to "3." Close the registry editor.
  4. Re-open the registry editor to ensure "3" is still there.
  5. Open Outlook. The Mailock add-in should now load automatically at startup and the blue Mailock ‘Compose New Secure Email’ button should appear in the top left-hand corner of your Outlook ribbon.
