I'm trying to connect my webmail calendar from roundcube to outlook. The webmail / imap connects flawlessly but outlook says I don't have a calendar. I am assuming that roundcube is using calDEV for the calendar and I've been looking online for options to sync. I was able to find some software to attempt this but it is giving me some errors. Is there any advice on how to get the calendar to show up on both my iPhone outlook app and on my outlook client?
