A few of our users used to be able to Send meeting requests on someone's behalf when using Exchange. This doesn't work with ZCS with Outlook 2003 or 2007. I checked the webmail version of the program to try to do it to see if it worked there and it didn't as well but in the HELP section of the webmail it shows that this is feature is supported.

Each user has full admin access to the other persons mailbox. They are able to send normal e-mails on behalf of the person but not calendar meeting requests. Is this a known issue or is this simply not supported in Zimbra at the moment and the help file is wrong?
