I have to echo what kevindods wrote. The lack of response to this issue is disappointing and really should have been addressed in a meaningful way in a more immediate manner, whether this program be freeware or not. I'm not a techhead but know enough to get through intermediate issues. Even though I have a working copy of the old software version on my laptop (which I didn't attempt to update) this issue has left me ready to move on to using Gmail online or using Thunderbird on my desktop.
That's a shame because, although I have no right to expect anything from software provided for free by an etheral nonentity, I have been a long-time strong supporter of adaption of programs such as Zimbra. I generally don't work for a big corporation or even a medium or small one, I work with small nonprofits which not only benefit from freeware but could help in their development as a testing bed. But like me, most nonprofit employees aren't terribly tech savvy and have a taxing job to perform that is not focused on IT. They need the software to work. Most nonprofits don't have IT employees, and just rely on that one person in the office brave enough to take the task on. But we use software to make our jobs easier, as a tool, we don't want software to be a lifestyle and trying to fix it to take hours on end of install, failure, report, uninstall, reboot, reinstall, reboot, failure, report, uninstall....
So my disappointment doesn't mean just one less user. It means one less advocate, one less strong supporter of open source, and because I need to be honest when the issue's brought up, bad
PR directly about Zimbra because of this experience. But maybe the Zimbra community wants it to stay a boutique effort. How quaint.
Whoever defended Zimbra against the original criticism was wrong. Apple or Microsoft would get royally slammed if this sort of botched release occurred and it would last in the press for a long time. Open source touts that, because of its community-base, it creates better product. Advocates against open source can point to this instance and create a considerable argument against such a statement.
