+1 I've been using Zimbra for a long time now (over 5 years) and it is rock solid. I can't say enough good about it. You don't actually **need** ActiveSync to sync your mail- IMAPS works just fine along with the other encrypted mail transports. There are other sync options for cal and contacts if you want to do that. I've tested then before and they do work but I personally don't normally sync those things so I can't speak to their long term reliability. They were fairly new some years ago when I tried them out so ActiveSync is probably the way to go for the best reliability and availability. That said, it appears basic ActiveSync is now included in the standard version of Zimbra 8.8 (https://blog.zimbra.com/2017/12/whats-new-zimbra-collaboration-8-8/#mobile). Zimbra also now has an internal "Chat" (XMPP compatible) and "Drive" function so it really is becoming an alternative to G-Suite. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Keith C. Perry, MS E.E.

Years ago I tried using all the open source calendaring solutions, CalDAV, etc. and/or email but nothing worked, and basically wasted hours of my time. The thing is, Active Sync is the only product that seems to work in a reliable way across all devices ( because so many people use Exchange) , so using a product with ActiveSync just works. For a company $20/month/user is so cheap you should be jumping. Note that corporate features such as legal archive/hold and trash retention can also be added - and if your using open source I'm not sure how you comply with any of those legal requirements. Of course that isn't a problem until your company is part of a legal action, but by then it's too late to add a hold because users or corp officers delete email. Note that the IT person may be responsible for keeping email from being deleted even by officers - ask your corp counsel. Legal hold provide archiving of all users email for the time provide in your corp policies. This way users email is preserved even if they delete it themselves. If your company is notified of a pending legal action and you don't prevent users from deleting messages, your company is likely in much more trouble. Most small companies are completely un-prepared for the legal holds required of email, etc. Corporate wide search is also available so you can provide that search tool to your legal team to pair down the amount of emails provided. Much better to only provide emails requested, then provide ALL of them. Note I don't do the legal stuff myself, I just have an attorney in the family that I've discussed email requirements at length, and it seems only the large companies really understand this. I do encourage small companies I deal with to setup email archiving and search up front so it can be used when required. Lee PS: If your willing to provide your own support to users, you might be able to get reseller account and provide this hosted service to internal users at much less than the pricing above. You can talk to me off-list for more info. ----- Original Message ----- > From: "Greg Helledy" <gregsonh@gra-inc.com> > To: "Philadelphia Linux User's Group Discussion List" <plug@lists.phillylinux.org> > Sent: Friday, December 15, 2017 3:03:24 PM > Subject: [PLUG] CalDAV server on linux > Our company needs a calendaring system.
