Apologies, it looks like the "hide in GAL" option is actually a property of the underlying object that the alias points to, not of the alias itself.
if you search bugzilla for "alias" with component set to ZCO, you'll find a bunch of bugs, most of them fixed, related to alias behavior with ZCO. It's not immediately clear what the behavior currently is by design.
Due to problems caused by aliases (particularly with CalDAV clients), we rarely use them. Instead, we create single-user distribution lists, which give us more control over display, etc. I'm not sure it'll help but it might be a solution. |
