I'm looking for a new groupware solution (mail, contacts, calendar, files) for myself and family members. ATM I'm using a combination of roundcube as webmail and icloud for contacts/calendar, dropbox for files and iOS for mobile access. This solution isn't really convenient, esp the access via web interface (no access to contacts/calendar)
I already looked for alternatives, but I didn't really find anything suitable. Mostly they are too oversized or not easy to integrate (e.g. Kolab)
What are you using?
