8. Important changes for Davmail users
Users of DavMail (for example Thunderbird/Lightning users) accessing Oxford Nexus should have experienced a change on 14 February 2012. In order to continue to access calendar information for your Nexus mailbox you will need to do one of the following:
- Use Outlook Web App, or a calendar client such as Microsoft Outlook (Windows or Mac). and, once your mailbox has been upgraded, check that your DavMail client is set to use Exchange Web Services (EWS, see below).
- reconfigure your DavMail client twice (once on 14 February and once following the migration of your Oxford Nexus Mailbox).
N.B. In some newer versions of Ubuntu, within the Default Unity desktop for instance, there is no system tray to launch Davmail. It may be necessary for you to manually edit your Davmail properties file to configure the correct URL and Exchange protocol settings. The settings probably looks something like this:
In order for DavMail to work with Exchange 2010, the Exchange protocol used must be EWS. EWS is a requirement for Exchange 2010 as support for WebDav has been dropped. Find the Exchange protocol settings in your DavMail configuration and ensure that EWS is used and "WebDav" is not. This change can be made on 14 February alongside the "legacy." addition, or you can choose to make the change when your mailbox is upgraded (i.e. when you remove the "legacy." and add "davmail.").
Instructions for configuring Nexus Calendars in Thunderbird using Davmail and Lightning are given on the OUCS web site.
