Yeah, I'm not saying it is perfect, nothing is. Zimbra standard also includes active sync so your iOS and android device can connect to it like if it was an exchange server. I have dozens of users doing that and the calendars work as intended. I also have a few dozen users connecting to our zimbra server via the Apple calendar program via CALDav protocol and although Apples program is not 100% CALDav compliant it works fine for the things people actually use. They send invites and get reminders for events just fine. For our outlook users there is a connector that allows outlook to connect to our zimbra server as if it were an exchange server. I wasn't aware that thundebird had a calendar component but it works fine for IMAP and POP. I'm not saying it is perfect but if you have a mix of platforms like I do(Windows, Mac, Linux, android, iOS) and have to host the data yourself, I think Zimbra is a decent solution. That being said, I would prefer to use googles offerings. It would make m
y job a lot easier. Being an email admin, dealing with spam/phishing/malware, maintaining security patches, OS updates, and hardware sucks.
