This also happens if I run a vm with windows on, indicating that it's not a browser issue. On all of the other macs the login appears, which indicates that the mac is talking toĮxchange correctly. When run on this machine, however when I navigate (with any browser) to I get a 403 error and no popup login screen. This is because outlook cant access the server correctly.
Outlook 2011 can't access the autoconfigure and manual config fails to communicate with our exchange server (2010 SP1 >rollup 4) and gives the error code -18597. It appears to be the same in every aspect of the network config as the working machines. My machine is a clean install, picking up our network setting by DHCP (as with the working machines). On our network there are other newer macs (imac and macbook pro) running the same software version of mountain lion that do not experience the same problem.
I have a very odd problem with a Mac Pro early 2008 model running mountain lion 10.8.4 (12E55).
