Your Questions, Answered
The free version allows users to create and edit calendars with up to 15 entries per calendar. There are no time restrictions or trial limits. If you need more than 15 entries, a paid license is required for each user performing those actions.
Owners and editors are users who create new calendars or add/edit events. Viewers only need to see calendars in read-only mode and do not need a license.
Yes! Simply install the app and start adding events directly in Teams. You can color-code and tag events, assign permissions, and share the calendar instantly with your team.
It depends on where the dates come from. Choose Virto Shared Calendar when your team types the entries in itself and shares the calendar with people outside the company: the team's time off, an on-call schedule, project dates for a client. Choose Virto Calendar App when the dates already live in Outlook, SharePoint lists or Planner and should appear in one calendar by themselves, for example absences collected from everyone's Outlook calendar or vacation requests approved in a SharePoint list. Virto Shared Calendar stores its entries on Microsoft Azure, managed by VirtoSoftware; with Virto Calendar App the data stays in your Microsoft 365 tenant.
Yes. The Virto Shared Calendar documentation on docs.virtosoftware.com has a Templates section with four setups described step by step: a vacation and absence calendar, an on-call schedule, a project deadlines calendar and a company calendar. Each one lists the categories, the permission settings and the public holiday calendar to add.
Yes! Create a calendar, enable sharing in Calendar Settings > Sharing Tab, copy the link, add the app to Teams, and paste the shared calendar link.
Outlook calendars are business classics — but Virto boosts your Teams shared calendar experience by adding real-time sync, anonymous access, and visual tags, all within Teams.
Inside your organization, yes by default. A new calendar is visible to everyone in your Microsoft 365 organization who uses the app, and in the Default permission mode everyone can edit it. You can switch the calendar to Restricted to choose who edits it, or mark it private. People outside your organization see it only through a view-only or editable link that you share.
No. External users do not need Microsoft accounts. Using Virto's anonymous sharing feature, you can send them a link with view-only or editable access without logging in.
Built-in calendars don't allow anonymous sharing or real-time sync across web and Teams. Virto Shared Calendar solves that.
Yes, choose between view-only and edit access for each calendar link.
Yes! Virto's Microsoft Teams shared calendar is fully responsive and works seamlessly across desktop, tablet, and mobile devices.
