LawVu Add-In - Deployment through Office365 Admin Centre
If LawVu users are unable to install Outlook Add-ins themselves, then it can often be installed and deployed like any other Microsoft Office Store add-In, by utilising the Office365 admin centre.
In the Office 365 Admin Centre, go to Settings then Integrated Apps. Click on Get Apps:
Search for LawVu:
Select the target user or a user group:
This will automatically deploy the Add-in to the selected users and will make it available in Outlook or Word.
If the Add-In is not available after the deployment for the users, please check if there are any security policies both across the organisation or on individual user machines that would prevent access to the Microsoft Office Add-In Store, or use of Outlook Add-Ins.
