You can export the ActiveCollab Calendar to your calendars, such as Google Calendar, OS X Calendar, Outlook, or any application that supports iCalendar.
- Go to "Calendar" on the left side ActiveCollab menu,
- Choose a Project calendar and hover right next to it, so you can see the ''Export'' button,
- Choose how you'd like to export your Calendar, ''Subscription link'' or ''Download .ics file'',
- Upload the link/file to your calendars.
Note: The calendar will update automatically, but you’ll only be able to Add or Edit events from ActiveCollab.
