Hi there, we are currently using Zarafa for us and our customers for about 3 years.
In general it was running but I never was happy as there are a few closed source parts in Zarafa. Not because of the price (it's not expensive). The Outlook client often has issues (mostly shared calenders not showing) after Windows-Updates. Usually you need to wait a few days until there is a working release available from Zarafa. Other than that, Users usually never had an issue using Outlook as it looked like it was connected to Exchange for them expect an additional Zarafa tab. There is no carddav support by default, you have to integrate it yourself with sabre-zarafa, a plugin (not from Zarafa). The xmpp-Implementation never really worked. It just works if the lefthandside of your mail is also your xmpp login. The webapp is quiet slow and (imho) ugly, as they try to rebuild Outlook in the Browser a little bit... The updates were usually painless and without issues, but since their announcement about stopping the outlook client, i think the complete quality is not the same anymore. Outlook support was the main reason we were running Zarafa, as most of our customers use Outlook. But since that decision, we think there are better solutions. For me the main reasons for SOGo are: *) if you use MAPI you don't need buggy connectors *) multiple users from different sources (LDAP, SQL) are easy to implement if you have to *) a real, proven IMAP Server can be used (Zarafa has it's own, feature-less IMAP-Server, we love Dovecot) *) Thunderbird Plugin seem to work quiet well and can replace outlook in my opinion *) easy integrated backup and restore mechanisms *) great clean webinterface with good features, but not useless things. *) in the debian repos (mostly, if you don't need openchange) *) completely free software but there is support from inverse if you need *) upgrading (seems to be) easy and without issues We think about not using openchange for these reasons: *) you have to use the inverse samba package, so no repository package anymore *) openchange seems to have still issues and we believe we'll never get happy to provide "half of an exchange", so we try to convince our customers to use something that is working ;-) (please correct me if I am wrong) *) keep it simple... (imap, card- and caldav is something other clients can do as well) What I would love to see in SOGo is an integration of Owncloud in the Webmail, that would be nice and handy to store/attach files to messages.
