[Evolution] Bug#798970: evolution: exchange server imap: sent mail folder not working properly

[wim]

Package: evolution
Version: 3.12.9~git20141130.241663-1+b1
Severity: normal

Hallo,

as the topic says,
the imap sent mail folder has some problems in evolution.
the mail server is an exchange server, connecting with k9-mail on android these problems do not exist.
- the folder is empty in evolution (1)
- very often messages are not copied to the imap sent mail folder, but their fallback folder, the local sent mail folder
- if they are copied to the imap sent mail folder, then cf supra (1)

when using a webclient on the exchange server, 
the sent messages which were not copied to the local folder,
are present in the imap sent mail folder;
but the evolution imap sent mail folder stays empty
(yes, it is the same folder)

hth,
Wim
