We have a setup where we have Exchange doing mail and calendaring. I have just set up Zimbra to offer an alternative (and far superior, especially for those of us not running Windows) calendaring experience. Everything is working great except for one thing...
When an appointment is created in Zimbra and the invite sent to a user, Exchange intercepts this and gives a link to its own webmail calendar area instead, with the result that you'll have two users with a shared appointment on different calendar systems. Is there a way to change the format of the invite to not have this happen? (Not sure exactly what content is triggering it, but I imagine some headers or something.)
