I have a user who for all intent and purposes has blocked another user. Not sure how this was done or how to unblock them... Basically I have 2 users trying to IM each other on cisco jabber but neither can. When I uninstalled and reinstalled jabber and click on the user i get this message
You have blocked this person or their domain from seeing your status or sending you messages. You are not able to send messages to blocked users or domains.
Any ideas? I logged into the CUPS server but do not see anything that can unblock or block.
