I noticed yesterday that the web user interface for sharing doesn't work anymore-- neither from a right click on a folder (mailbox or contacts) nor the properties "Add share..." button. I've tried it from IE6+7 and FF3 on both Windows and Linux.
Sharing is enabled in the COS. Nothing in the logs that I have noticed. Did a zmcontrol stop+start for good measure. I haven't seen any other posts or bugs like this and am currently at a loss to explain it. Any suggestions?
