Hi List; I'm hoping someone can help with this. I'm running evolution at a new client site to connect to exchange. (I've changed all instances of my actual username to 'myusername' and all instances of the clients domain to 'domain' in the data presented below) I have the following settings: username: DOMAIN\myusername OWA URL: https://owa.domain.com With these settings I can pull my mail with no issues, however I cannot access the global address book. I've entered the "Global Catalog Server Name" as the name of the exchange server: domainex-1.city.domain.com With this setting if I go to 'Contacts --> Global Address List' I get this error: =================== Error loading addressbook. We were unable to open this addressbook. This either means you have entered an incorrect URI, or the server is unreachable ==================== I can ping the server. If I start from the command line I get this at startup time: ===================================== $ evolution CalDAV Eplugin starting up ... (evolution:14554): e-data-server-ui-WARNING **: Key file does not have key 'exchange:__myusername;auth_NTLM@xxxxxxxxxxxxxxx' evolution-shell-Message: Killing old version of evolution-data-server... ** (evolution:14641): DEBUG: mailto URL command: evolution --component=mail %s ** (evolution:14641): DEBUG: mailto URL program: evolution ** (evolution:14641): WARNING **: LDAP authentication failed (0xffffffff) ====================================== When I click on the Global Address book I see this at the command line: ==================================== (evolution:14641): eab-widgets-WARNING **: EABView at present does not support multiple writes on the "source" property. ====================================== Thanks in advance
