Collaborative Calendars for Business

Updated: June 29, 2019

2019. Slack integrates with Office 365



Slack announced new integrations with Microsoft OneDrive and Outlook. Specifically, Slack is integrating calendar, files and calls and bringing in integrations with other services, including Box, Dropbox and Zoom. For starters, the company is announcing deep integration with Outlook that enables users to get and respond to invitations in Slack. You can also join a meeting with a click directly from Slack, whether that’s Zoom, WebEx or Skype for Business. What’s more, when you’re in a meeting, your status will update automatically in Slack, saving users from manually doing this (or more likely forgetting and getting a flurry of Slack questions in the middle of a meeting). Another integration lets you share emails directly into Slack. Instead of copying and pasting or forwarding the email to a large group, you can click a Slack button in the Outlook interface and share it as a direct message with a group or to your personal Slack channel.


2017. Google Calendar improves integration with Microsoft Exchange



For companies that use both Google’s G Suite and it's Microsoft alternative - Exchange in parallel, the new Google Calendar update arrived. G Suite admins can now allow their users to see real-time free/busy information across the two systems. This means tools like Google Calendar’s Find a Time feature and Outlook’s Scheduling Assistant can now easily talk to each other, for example. Once an admin has enabled them, these new Calendar Interop features will be available on Google Calendar for Android, iOS and the web, as well as all Outlook 2010+ clients on desktop, mobile and web.


2017. Todoist launched integration with Google Calendar



Task manager Todoist is launching a deep two-way integration with Google Calendar. After hooking up your Todoist account with Google Calendar, your tasks are going to show up in your calendar if they have a due date. If you also entered a specific time of the day, you’ll see an event in your calendar. Recurring tasks will create multiple events. After that, you can click on your calendar events, edit them, move them around and everything will be synchronized back to Todoist. This way, you get a calendar view of your tasks… in your calendar. It’s also a good way to let other people add stuff to your calendar thanks to shared projects.


2010. Zoho Calendar - the best online calendar in the market



Today, Zoho updated its Zoho Calendar and released it out of beta. And Zoho's chief evangelist, Raju Vegesna, called this service the best online calendar in the market. Given that he is a modest person, and Zoho never promoted its products with loud statements, perhaps, this is true. At least, this service is no worse than Google Calendar, simply because it's a complete clone of Google Calendar. Zoho Calendar allows to create multiple calendars, share them (with different access levels), set reminders (by email, RSS), send invitations, embed public calendars on your site / blog. It has a plugin for Outlook (for synchronization), mobile version and supports offline access with Google Gears. Calendars can be synchronized with external services via ICAL protocol. And of course, Zoho Calendar is tightly integrated to other Zoho services (CRM, Projects, Planner, Mail, Chat).
