I've tried all of the "tips" given here, but Zimbra keeps loading whenever I login with Internet Explorer.
It does NOT do that when I use Firefox.
Can you not have a Webmail version which can use more than one browser, like most good software does???
This Webmail has been a constant headache ever since I first opened an account with it, and only seems to be stable for relatively short periods.
I do not like the Zimbra version at all, and if I could be sure that I would not lose my E-mail altogether I would move it to another client.
