So I use calendar invites all the time, to keep myself organised, and keep the client aware of what's going on too.
I keep many of my clients available in the contacts section, including their address, because it's super convenient, and also syncs with my phone.
That being said, the location section of a Calendar Invite seems to only be populatable by Locations that are manually defined in the Zimbra environment, which makes sense for meeting rooms. However, I really would like it if I could have the Location function ALSO pull from known contacts, so I can conveniently enter the address of a site the meeting is about (client site?).
I suspect this shouldn't be too hard to implement, but is there any chance we could see this happen some time?
