I have zimbra on 2 different servers for 2 different domains. I want to share a calendar from say user 'a' on domain 'b' to user 'c' on domain 'd'.
I did the share calendar to 'external guests (view only)' with password and an email was sent to user 'c'. It showed up with the accept/decline buttons, I clicked accept, but never prompted for a password and appointments don't show up though calendar is added to list of calendars.
It seems like this should be possible, but I can't get it to work...
Anybody tried this?
