If Outlook disables the SmartVault plug-in to improve performance, Outlook will not reload it unless the registry key is fixed or the add-in is completely re-installed.
Resolving This Issue
If Outlook keeps deactivating the add-in, try uninstalling and reinstalling the SmartVault plug-in.
If it doesn’t solve the issue, do the following:
Note: Using Registry Editor incorrectly can cause system-wide problems that may require you to re-install Windows to correct them. Ensure you make a back up of your registry before attempting any changes. Do not edit the Windows registry unless you are confident about doing so.
1. Open your Registry Editor (run regedit.exe) and locate the following registry entries:
Note: For Windows 10 users, in the search box on the taskbar, type regedit.
2. Double-click on LoadBehavior and change the value to 3. This sets it to always enable.
3. Open Outlook. The add-in should now load automatically at startup.
