I just found out that the zimbra connector just crashed on me. I am using the 3.1 version of the zimbra connector. Now my outlooks goes into a loop of restarts and I have no idea how to get it to stop.
I tried uninstalling the zimbra connector and the outlook gives an error. And if I reinstall it, it prompts me for username, password and server name and then it prompts to restart the outlook application again.
