Disclaimer: iCal is a standard that has been amended by many different big vendors like Microsoft and Apple. We send in our calendar response attributes to tell clients, which are subscribing to sync or refresh every 1 hour. However, we can’t assure that the client is adhering to this attribute. Also, these attributes are different for every larger consumer (Outlook, Icalendar, Google calendar). Some of them let you choose the sync interval (e.g. MacOS X calendar), some don't. Most of them should sync within 24h. Don’t expect immediate syncing. Some of them likely and intentionally ignore any specified refresh rate to prevent DNS attacks.
Using the iCalendar integration, you can connect MindMeister with an iCalendar-compatible calendar app such as Outlook or Google Calendar. Once connected, all tasks from your mind maps that have been assigned a due date will be displayed in your calendar.
Please note that Google refreshes subscribed calendars about once every 24 hours. This means that it can take a few hours for new tasks to appear in your connected calendar.
How to connect a calendar
Open the "My Account" area and navigate to MindMeister > Integrations and click on the "Configure" button next to iCalendar.
On the next screen, copy the iCalendar Feed URL:
The place to insert the URL varies depending on the calendar app you're using. Here's how it works in Google Calendar:
1) Open Google Calendar and click on the Settings Menu icon, then select "Settings" from the dropdown menu.
In the navigation on the left, click on "Add Calendar" and then select "From URL".
Paste the iCalendar Feed URL that you've previously copied from MindMeister into the field and click on "ADD CALENDAR".
