Installing the SharePoint Calendar E-Mail Extension 3.0

The SharePoint Calendar Email Extension 3.0 extends your SharePoint Calendars and enables outgoing e-mail.

A quick introduction: What’s new in Version 3.0?

What people really missed in the previous version were two things:

  1. Support for recurring events, and
  2. Integration with Meeting Workspaces (including external attendees!).

Both missing features are now available. Other improvements:

  1. Communication, invitee/attendee’s status: The full range of status responses is now supported – no limitations or simplifications.
  2. Proposed time in case of tentative acceptance is improved.
  3. Time zone depends now in the web’s regional settings (previously system configuration).
  4. Meeting forwarding is improved.
  1. E-Mail body for invitations is fully configurable (HTML) and can be enriched with dynamic values from the meeting.
  2. Individual e-mail bodies for each instance of the Event content type, allows you to handle multiple Event types and mail bodies on one Calendar list.
  3. External server name for workspace links, if you use different server names for intranet and internet/extranet. To access your workspace from the internet and have the right link in your meeting’s description.
  4. Some improvements concerning receivers and type registration on feature activation and so on.


    Log on to one of your SharePoint farm’s server as an Administrator. Download the setup to a local folder and unzip the folder CalendarEmail. The content should look like this:

    Install the new Framework, run SetupFramwork.exe

    You can check if this version of the SharePoint Framework is already installed when you take a look at the installed and deployed farm solutions in SharePoint central administration. Setup will do this for you anyway. SharePoint Calendar E-Mail Extension 3.0 is built on the 2.2.1 version of the SharePoint Framework. It’s very likely that you have 2.2 or 2.1 already installed. 2.2.1 is published for the first time with SharePoint Calendar E-Mail Extension 3.0.

    Install the Solution, run Setup.exe

    Now you’ll need your license key. A trial key (30 days) is always available from the download button at the product page: /calendar-email-extension.

    If you have no access to the internet the setup will not succeed. But you’ll find a file named[3.0].xml in the setup directory. The file is created during setup and is designated to support offline key validation. Take this file, attach it to an e-mail and send it to We’ll return the validated file plus instructions as fast as possible.

    You’re now finished with installing the solution.
