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:
- Close Outlook (and all other Office programs to be sure). Make sure the "OUTLOOK.EXE" process is not running in the Windows Task Manager
- Open the registry editor again. Double-click the registry key to edit it.
- Change the Load Behavior to "3." Close the registry editor.
- Re-open the registry editor to ensure "3" is still there.
- 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.
