Calendar App 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.

Works reliably. I've been looking for something like this for a long time to combine Outlook and SP calendars. This feature was the prime requirement and cost was not a factor. The performance and price could hardly be better.

The interface and functions may seem be a little complex to the novice user, but I love this calendar's function to "overlay Exchange Online shared calendars" which saves an unbelievable amount of time from having to view all your existing calendars or re-input your data into all of them.

Nice layout work, intuitive design.

I have worked with the Virto Calendar team to get this set up in an enterprise environment and I cannot brag enough on their support team! They have done everything in their power to ensure my enterprise is happy with this application and the licensing structure around large tenants. Virto really knows how to treat customers in my opinion.

Great tool! I was able to overlay my SharePoint, shared Exchange calendars and meeting rooms availability on SharePoint within couple minutes. Very simple to use and fast working product.
