Integrating Guusto with Microsoft Outlook allows employees to recognize colleagues and access Guusto without leaving their inbox. Once deployed by your Microsoft 365 administrator, the Guusto add-in is available directly within Outlook across supported platforms.
Before you begin
To deploy the Guusto Outlook add-in, you'll need:
A Global Admin, Exchange Admin, or Microsoft 365 Admin role
Access to the Microsoft 365 Admin Center
An active Guusto account for each user, using the same email address as their Microsoft account
Note: Changes made in the Microsoft 365 Admin Center can take up to 24 hours to take effect. Users may also need to restart Outlook before the add-in appears.
Step 1: Open Integrated Apps
Sign in to the Microsoft 365 Admin Center (
admin.microsoft.com).Navigate to Settings → Integrated apps.
Step 2: Deploy the Guusto add-in
Click Get apps.
Search for Guusto Rewards & Recognition.
Select the Guusto listing.
Click Get it now.
Step 3: Assign users
Under Assign users, choose who should receive the add-in:
Entire organization, or
A specific group if you'd like to pilot the deployment first.
Review the requested permissions.
Click Finish Deployment.
What your users will see
Once deployment has completed:
Users can access Guusto directly within Outlook, eliminating the need to switch to a web browser.
