Virto Calendar App by Virto is licensed depending on the number of users with edit and read-only permissions.
For example, you plan to let ten users work with Virto Calendar App. Two of them will have edit rights, and eight of them will have read-only rights. You need to purchase ten licenses for all Virto Calendar App users, even though some will have read-only rights.
You can find details about your current subscription in the “Subscription” tab under the gear icon.

The Virto Calendar App license allows you to use the application in three ways:
- In any browser window as a web application by visiting https://calendar-app.virtosoftware.com/.
- Directly on your SharePoint site, added as a web part.
- In your Microsoft Teams, after being added as a separate tab in any channel.
Auto-assignment feature
Virto Calendar App has a built-in auto-assign system. When a user without a license is trying to access the app, they can get the license automatically if there are some purchased unassigned licenses. The feature is activated by default, you can disable it in the “Subscription” tab in the Virto Calendar App settings (under the gear icon).
30-days clearing feature
When auto-assignment is active, you can also apply the 30-days clearing feature. If licensed users don’t use Virto Calendar App for more than 30 days, the system automatically unassigns them.
