Comment 2 for bug 174208

I just noticed that Bug 408158 filed against Thunderbird also requests eds support. I don't think this bug (against Calendar) is a duplicate.

Read-only calendar support is possible through a work-around:

Add a Remote Calendar using the URI: file:///home/[username]/.evolution/[path_to_ics_file]

For example:
'file:///home/mjohansson/.evolution/exchange/mjohansson@spam+domain.com/personal/subfolders/Calendar/subfolders/My Calendar/cache.ics'

'file:///home/mjohansson/.evolution/calendar/local/system/calendar.ics'

I've only attempted either of these in read-only mode (which can only be set in the properties after creating the remote calendar).
