I work for a university that has just moved to a Zimbra system. I have some faculty trying out the Zimbra Desktop application to see if it would meet their needs over Outlook, which some of the IT staff would like to get rid of.
Here are some comments I have received thus far:
*Need the ability to set up shared calendars, invite users to calendars, and accept shares from this app.
*Spell check...no need to say more
*This may be a "Zimbra as a Whole" issue: Need to have a return receipt option.
*Would it be possible to have the option to show a short list of your tasks on the email interface, just above the calendar?
That is all I have at the moment.
