Getting started

Getting started

Getting 3e Calendar up and running is easy and no hassle process. Perform following three simple steps to make 3e Calendar ready to use. Then use calendar in a regular way – create events, manage calendars, schedule meeting, send invitations etc.
Step 1Setup calendar server

You need 3e Calendar server to store calendars, events and other calendar data for your users. You can get it as either on-premise package and run it on your own or as cloud based hosted service provider by Zonio.

Step 2Create user accounts

Once you have a calendar server it must be populated with users. You can create accounts and groups manually or connect calendar server to your corporate LDAP directory and synchronize accounts, groups and aliases automatically.

Step 3Install plugins

A plugin into supported calendar apps must be installed for each user to access calendar data in 3e Calendar. Calendar data may be accessed from almost any even unsupported calendar app or device via a web subscription.

Supported calendar apps
