Expunge Function Not Working as Expected/Needed
Referring to this thread evolution-ews#124 (closed) I don't think the Expunge function does what it is supposed to do. The current Expunge function does the same (if it does something at all) like the Empty function: it moves files to the Deleted folder (basically a soft-delete). IMO there is no value of Expunge if it does not hard-delete a folders content - especially the Junk folder.
