Introducing Mailfence Calendar: a secure online calendar to schedule, manage and track meetings & events

Mailfence strives to make the internet a safer place. That’s why we developed our encrypted email solution. But in our opinion just offering secure and private email is not sufficient. Otherwise, our users would need to use insecure solutions to manage their appointments, create and store their documents or chat online. Luckily Mailfence is much more than a secure email. Mailfence allows you to organize your life through powerful productivity tools such as Mailfence Calendar, Mailfence Documents, Mailfence Contacts, Mailfence Groups, Mailfence Chat and Mailfence Polls. Therefore, in this post, you will discover how to schedule, manage, and track meetings & events with Mailfence secure calendar.

What is Mailfence Calendar?

Mailfence Calendar is a powerful online calendar application that allows you to schedule, manage, and track your meetings & events.

With Mailfence Calendar you can:

  • Manage your personal calendar
  • Share your calendar with members of Mailfence Groups
  • Share your calendar publicly (Public access)
  • Access other calendars: calendars of Mailfence Groups members, group calendars or external calendars (from other providers)

You can consult your Mailfence Calendar via our web interface but also via dedicated calendar applications on desktops and smartphones.

How can I use Mailfence secure online calendar to collaborate with colleagues, friends and family?

You can use Mailfence Calendar both to schedule meetings with other Mailfence users, but also with contacts that do not use Mailfence. Moreover,  to collaborate with other Mailfence users you need to be member of the same Mailfence Group.  Learn here how to create Mailfence groups.

An event is turned into a meeting when you invite participants. These participants are selected among group members and contacts (only contacts with an e-mail address can be selected).  Main features are:

  • Create a meeting
  • Pending meetings
  • Accept or decline a meeting
  • Invitations follow-up (re-sending meeting invitations)

How can I access my Mailfence secure online calendar on other devices?

Your mailfence calendar can also be accessed and managed via specific Calendar Apps either via mobile synchronization (Activesync Exchange) or via CalDAV.

Access via CalDAV

Calendars can be accessed with read and write rights from CalDAV compliant third-party-software such as Lightning, Apple Calendar (macOS), or iPhone/iPad.

You will find detailed information about features, limitations, support for meetings, and configuration in our online help.

If both your subscription and your device (computer, smartphone, tablet) can handle ActiveSync synchronization, we advise using the latter. For example, set-up is easier, there is only one set-up for all tools (email, contacts, and calendar data) and synchronization is more robust. However, unlike CalDAV, it does not handle group members and group data.

Access via Activesync Exchange

You can also synchronize your smartphone apps (iPhone, iPad, Android, BlackBerry, etc.) with your Mailfence Messages, Calendars and Contacts.

You can even synchronize your Mailfence Calendar with several devices meanwhile Mailfence being the synchronization server.

Should a problem occur during the synchronization process (lost connection, power failure, etc.), the next synchronization will assume that up-to-date data are on Mailfence. This synchronization keeps the data already present in your smartphone.

You will find detailed information about features and configuration in our online help.

Access via RSS

RSS will notify you of new items on a Website, RSS is used in a RSS reader. Then you subscribe to RSS feeds and the RSS reader will refresh them periodically.

Mailfence offers several feeds, all protected by your usual login and password.

Each (private or group) calendar has 4 RSS feeds:

  • Today
  • This week
  • This month
  • 30 days (from today)
Where to find feeds?  Click on ‘My calendar’ and then select RSS.

Import and export calendar data


Before importing, select a private or group calendar. Select Import in the Actions of the current calendar (click on the ‘…’ of the calendar top menu). 2 import modes are available:

  • Import from a file: the file must be in the vCal/iCal format
  • Import from Google Calendar: this will import all events

In both cases, make sure that your Mailfence calendar can accept the number of events to import.


Select a private or group calendar prior to exporting.

You can export one, several or all the events from a calendar in vCal/iCal format to reimport them in software compatible with this format:

  • Export only one event: do a ‘right click’ on the event and choose ‘export’
  • Export several events: select a view (day, week, or month) and select Export in calendar Actions. Select Events on this page.
  • Export the entire private calendar: click on Export in calendar Actions. Select All events of this calendar.
  • Export in PDF downloads all events from the current view.
