Anyone facing an issue whereby users of Zimbra Desktop can no longer login to their web client unless they switch from advanced to standard mode? Zimbra Support suspect this: We have checked provided log files and found continuous DoS alerts for IP "x.x.x.x" where from user xxx connecting ...

I believe there is some serious bugs with Zimbra Desktop, because I notice that all users who are complaining slow AJAX web clients are all ZD users. When restoring their accounts from backup, there is no such issues anymore. See this: viewtopic.php?t=56551&start=10

User on Zimbra Desktop 7.3 now feedback that his webmail on Chrome can no longer login unless he switch to standard HTML version. Even so, it's not responsive at all. I hope this has nothing to do with Zimbra Desktop issue.

One of our shared user account with a huge 50GB mailbox size and shared to many users is extremely slow. When clicking on an email, it could take about 5 seconds for the email content to show up. Is there a size limit for a Zimbra account? Is it possible to "archive" older emails into anot...
