I'm involved in a project at work looking at using Linux Desktops for as yet to be specified users... One of the general use issues that I can't yet resolve is searching Global Address Lists using Thunderbird. I have email working using IMAP/SMTP and calendaring using Lightning and Exchange EWS plugin. I can't, however, get anything out of GAL. This is what I've been basing my attempts on: http://exchangetips.us/2013/03/accessing-the-global-address-list-from-mozilla-thunderbird/
Has anyone had any success in getting GAL searches to work? Any tips would be much appreciated!
