With IMAP you can only access your email, not your calendars, contacts, or tasks. It is possible that you will be prompted with a security warning concerning the fact that your incoming/outgoing settings does not use encryption and here you should check the ' I understand the risks' check box and then click on the Done button.Thunderbird lacks Exchange support so it needs to be configured for IMAP. The last thing you need to do is to simple press the Done button so the changes can be saved. Please choose the Normal Password authentication method from the last drop-down list of the Outgoing configuration group.

Last but not least is the Authentication method that should be used by the client when authenticating in front of the SMTP protocol. Please choose the None option as there is no SSL encryption on the default SMTP port. Then you will need to choose the SSL encryption for that protocol. By default the SMTPservice is using port 25 and you should be able to select it from the Port drop-down. Once you are done with the hostname, please configure the Port of the service. If your domain is for example the hostname you will need to use is. It is relatively simple - the hostname is where the substitution should be replaced with your actual domain name.
