If you find the Mailock button has disappeared from the ribbon the most likely reason is that Outlook has removed it.
Outlook monitors its add-ins and deactivates any it believes are causing any issues. Usually, there is nothing wrong with the Mailock add-in, other than Outlook believes it is taking too long to start.
To get the button back, the first thing to do is to check how Outlook has deactivated the add-in:
In Outlook, click on 'File' at the top left:
Next, choose 'Options':
Followed by 'Add-ins':
This takes you to the list of all add-ins in Outlook. Look for one called 'Beyond Encryption' in either:
- Inactive Application Add-ins
- Disabled Application Add-ins
Once you've found it, follow the corresponding steps below.
Inactive application add-ins
This can occur if the add-in has caused an error, but not one that caused Outlook to close, or if Outlook thinks the add-in is taking too long to start.
- In Outlook, click the ‘File’ tab
- Click the ‘Options’ button
- In the categories pane, click ‘Add-ins’
- In the details pane, verify that the ‘Beyond Encryption’ add-in appears in the 'Inactive Application Add-ins' list
- In the Manage box below the list, click ‘COM Add-ins’, and then click ‘Go’
- In the COM Add-Ins dialogue box, select the check box next to the disabled ‘Beyond Encryption’ add-in
- Click ‘OK’.
Disabled application add-ins
This can occur if the add-in has caused Outlook to close unexpectedly.
- In Outlook, click the ‘File’ tab
- Click the ‘Options’ button
- In the left-hand pane, click ‘Add-ins’
- In the ‘Manage’ box, click ‘Disabled Items’, then click ‘Go’
- Select the ‘Beyond Encryption’ add-in and click ‘Enable’
- Click ‘Close’
- Return to the Manage box, click ‘COM Add-ins’ and then click ‘Go’
- Click in the box to the left of the 'Beyond Encryption' add-in and click ‘OK’
- The window will close and you'll see the Mailock button back on your ribbon
