Calendar Overlay Pro for Office 365 Customers

Implementing Virto Calendar for SharePoint Online was a no brainer for my team. After a free trial, we quickly saw what an amazing solution it is. We have been able to extend SharePoint's out of the box calendars with this app to create beautiful, interactive calendars. We even developed a conference room booking system for one of the premier sporting facilities in the US, based on the features available with Virto Calendar. The Virto team is also very quick to add new features to the application. I have seen it evolve over the past 2 years into an app we just can't live without. It seems they listen to their customers and implement the features that are needed most and lacking in the default SharePoint calendaring experience. I could not recommend a better app for SharePoint online calendaring.

In my opinion, that is the best calendar app for ms teams! It has nice layout work, intuitive design, and a wide range of customization features. I really love the “Mini-calendar” feature to have a compact view of all my events. And it's great that the app also supports recurring events for Outlook and SharePoint Calendar data sources.

I have worked with the VirtoSoftware team for some time to get this teams calendar app installed into our enterprise environment. And I cannot brag enough about the support team! They did their best to ensure our employees were happy with this application and the licensing structure around many tenants. And now the solution suits our business needs most effectively. It also has a perfect MS Teams integration! It’s really convenient to create Teams meetings right from Calendar Events and manage all events without switching between the applications.

Great office 365 calendar tool. Always works reliably. I’ve searched for a long time for a solution to combine multiple calendars in a single view. This feature was critical for our company, making this tool the best calendar app for Microsoft Teams & Office 365 & SharePoint. The performance and price could hardly be better.
November 6, 2021
The interface and functions from the first sign may seem not so obvious to the novice user, but I love the feature of this Office 365 calendar tool to "overlay Exchange Online shared calendars," which saves an unbelievable amount of time. The ability to view all of the existing calendars or re-input your data into all of them – is vital for my work. My rate is 5/5.
October 7, 2020
Great scheduling solution! I could overlay my SharePoint and shared Exchange calendars in one centralized view and check the meetings room availability within a couple of minutes! Very easy-to-use and fast-working office 365 calendar tool.
