Hello Zimbra folks,
Probably the single most frustrating thing about using Zimbra for e-mail is that while uploading attachments, I cannot continue working on the e-mail message. While the upload window is active I can't type or do anything at all in Zimbra.
Put it this way: If uploading a 5MB attachment takes 30 seconds, during which I can't work, and I send this attachment in 30 separate e-mails throughout the day, I have lost 15 minutes of productivity that day.
With Google mail this was never an issue as I could continue working on the message while the attachment was uploading.
Zimbra needs to fix this.
