When I right-click on a calendar and select Properties from the context menu, an Edit Calendar dialog appears. In this dialog there is a drop-down box labelled E-Mail which lets me select the e-mail account associated with this calendar. However, the list contains not only my e-mail accounts, but also my news accounts. I don't see how selecting a news account here could possibly work with e-mail based scheduling, so their presence in the list is probably a bug. This problem is compounded by the fact that the accounts are listed only by e-mail address. If you use the same e-mail address for e-mail and news (as most people do), then you're going to see duplicate entries in the list, and won't know which one to select. I am using Lightning 2.6.2 with Thunderbird 24.1.0.
The piece of code that fills the list could be found here: http://mxr.mozilla.org/comm-central/source/calendar/lightning/content/lightning-utils.js#57 But as far as I can tell, there's no need to skip news identities there. They could also have an smtpServer configured and you can even select them composing a mail. I would rather use a similiar drop down list as in the message compose window, or simply add an icon in front of the name, as it's done in the folder pane. But I'm quite not sure which is the way to go here...
Well, if it makes sense to keep news identities in the list, then some sort of indicator which distinguishes them from e-mail identities would be great.
