We use Apple or Outlook calendars and I would like to know if there is a possibility to sync JIRA due dates into those calendars?
Our add-on "Issue Calendar Sync" allows you to put your JIRA issues into your personal calendars. All relevant dates can be seen in the calendar. It will automatically sync in real-time when you update an issue in the calendar.
You can find more info here: https://infos.seibert-media.net/display/PLUGINS/ICS+-+Issue+Calendar+Sync+for+JIRA
And here you got Issue Calendar Syn in Atlassian's Marketplace: https://marketplace.atlassian.com/plugins/net.seibertmedia.jira.plugins.issue-calendar-sync/server/overview
