Hi, I'm having trouble setting up the IMAP mail from my work exchange server in a fresh install of Thunderbird. Once I'd put in the server address Thunderbird retrieved all of the security settings, which I've checked agains the provided settings that are listed in the webmail. I've also used these settings to set up IMAP mail on my phone to triple check everything. However, in the account set-up screen I still recieve the message "Configuration cannot be verified - Is your username/password correct?" (again, I checked everything I was using independently and they were accepted). Once I got out of the initial set-up screen the error changed to the following: "The Kerberos/GSSAPI ticket was not accepted by the IMAP server <my email address>. Please check that you are logged into the Kerberos/GSSAPI realm." The only possibility that I can think of is that Thunderbird is trying to use my email address instead of the server to authenticate which is why I'm recieving the error. The mail address is xx@uu.nl while the server is soliscom.uu.nl. Any help or suggestions that anyone has would be welcome, Cheers.
