Intermedia Unite Outlook integration is delivered with Intermedia Unite Desktop App.

Feature is disabled by default, follow the steps below to enable it manually:

Scenario 1. User manually enables integration

Important: Admin Rights are required in order to enable Integration.

Click on your user icon in Intermedia Unite > Integrations, check the box for Microsoft Outlook integration, click Save Changes.

Confirmation with Windows admin permissions will be asked. On successful enablement, user will see Changes Saved notification and checkmark. Outlook restart is required to start using the Integration.

Scenario 2. Admin pre-enables integration

Administrator runs UniteOfficeIntegration.exe with -silentinstall key from Intermedia Unite installation directory with administrator permissions. In the table below you can find default installation paths for all installation types.

Application Installation Executable path Command
Intermedia Unite installed for all users C:\Program Files\Intermedia Unite\OfficeIntegrationServer\UniteOfficeIntegration.exe UniteOfficeIntegration.exe -silentinstall 
Intermedia Unite installed for current user C:\Users\{UserName}\AppData\Local\Programs\Intermedia Unite\OfficeIntegrationServer\UniteOfficeIntegration.exe UniteOfficeIntegration.exe -silentinstall

After that, user can enable integration himself. No admin permissions will be required. Outlook restart is required to start using the Integration.
