One of of our Zimbra 7.1.3 NE servers has issues when accepting a calendar share between certain users. It works fine 19 times out of 20, but that 1 time out of 20 is really wierd.
When trying to accept the share, there is an error popup that says "Access denied".
The strange this is, when I use my admin powers, do a "View Mail" login to that mailbox, I can accept it perfectly, every single time.
It is reproducable in the case that if it happens, I can make it work every time when using the admin view mail, then accept trick. What is not reproducable, is triggering the issue.
