Virto Calendar App review
A Microsoft-focused calendar app for combining organizational schedules and resources.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Virto Calendar App brings multiple scheduling sources into unified, color-coded calendar views. It is designed for organizations working in Microsoft 365, SharePoint, or Microsoft Teams, including teams coordinating personal, departmental, project, resource, and vacation schedules. The application is available through a browser, as a SharePoint web part, as a Microsoft Teams tab, or through enterprise self-deployment in an organization’s Azure environment. Its paid model makes it a better fit for organizations seeking a shared calendar layer than for individuals looking for a free personal calendar.
The main strength is breadth within Microsoft-centered workflows. Virto can overlay Exchange, SharePoint, Planner, resource, public-folder, and iCalendar data sources, while also connecting with Microsoft 365, Outlook, Microsoft Exchange, Microsoft Planner, Google Calendar, iCal, and Microsoft Lists. Users can create, move, delete, and reschedule events, create Microsoft Teams meetings from Outlook calendar events, and export SharePoint events to Outlook with iCalendar files. This combination supports scheduling across departments, projects, resources, and external feeds without limiting the calendar to one source.
Its view and access controls are suited to organizations with varied planning needs. Day, week, work-week, month, year, quarter, flat-year, and Gantt views provide different ways to inspect schedules, while customizable colors help distinguish calendar sources or event types. SharePoint-based permissions and external-user access add administrative control for shared environments. The trade-off is that Virto is a paid product with no free plan, and its strongest fit is clearly Microsoft 365 and SharePoint ecosystems. Organizations already invested in those platforms should consider it for consolidated scheduling; users seeking a lightweight standalone calendar may prefer a narrower tool.
