Product: Virto Alerts & Reminders App
Updated: 2026-08-12


The Virto Alerts App, formerly being the Add-in, has undergone significant changes. It now uses Azure for authorization, requiring users to grant [permissions](https://docs.virtosoftware.com/docs/alerts-and-reminders-by-virto/installation-and-system-requirements/permissions-required-for-application/index.md) to the app and update it accordingly.

## Authorization

The app now uses Azure AD for authorization. You may need to grant additional permissions:

1. Log in to Azure AD as a tenant administrator.
2. Go to the SharePoint site -> Documents, where the Virto Alerts App is installed.
3. Click on the ribbon and select "Virto Alerts".

4. Grant the required permissions for the Virto Alerts App to function properly.
