Zimbra Collaboration Suite features the most robust web calendar available today. It's designed with rigorous work environments in mind and allows users to easily share schedules and create group calendars. The complete web calendar functionality is available in both the ZCS Open Source and Network Edition client and server; it is an ideal groupware solution for any organization.

Rich Ajax-Based Web Calendar

With Zimbra Calendar you will quickly see how well the rich Ajax experience rivals traditional calendar clients like Microsoft Outlook or PeopleCube Meeting Maker, yet it's completely web-based. Some examples of what you'll find:

• Fast switching between multiple time views (Day, Week, Work Week, Month)
• Drag and drop to move events, "stretch" the events to change times or create multi-day "banners"
• Powerful event detail handling such as:
• Compose rich text meeting notes; add attachments to meetings
• Easily look up free-busy times of others, rooms, and resources
• GAL auto complete to quickly create meeting invites and share calendars
• Handy event reminder "toast" which appears throughout Zimbra Collaboration Suite

View Multiples Calendars and Group Scheduling

Zimbra Calendar lets you view multiple schedules as different color "overlays" in your calendar (they can be yours or ones shared with you).

• Each can be toggled on and off with one click
• Also add calendars as remote iCal feeds

There are two ways to set up group meetings:

• Add an event directly to one of your calendar overlays shared by a colleague (see delegated access and sharing below)
• Invite others, EG use 'Schedule View' to easily see free - busy times of your meeting invitees. Meeting invites sent automatically appear other's calendar; invites are also appear in their inbox where they are accepted / declined

Full Calendar Sharing and Delegated Access

Zimbra Calendar features the same familiar sharing UI and workflow as Address Book and Documents. With just one click on one of your calendars you can initiate sharing with:

• Workgroup peers (GAL auto complete)
• Others outside workgroup (send email, set password)
• Anyone publishing to the web as a read-only view (provides URL for others to use)

Also, you can set permission levels on calendar sharing:

• Read only or full delegated access
• Permissions can be set per user (everyone doesn't have to get same access)
• Each calendar can have different permissions

Server Supports Standards and Data Portability:

• ZCS server supports iCal and CalDAV standards allowing you to import external iCal feeds or connect standards-based like Mozilla Sunbird
• It also has complete REST / SOAP programming interface for making web services calls between ZCS Calendar and other web applications to share data
• Users of ZCS Network Edition also have additional native connectivity to other clients like Microsoft Outlook (MAPI) and the Apple Desktop iCal client (iSync) as well as to popular mobile device calendars via Zimbra Mobile.
