Description of problem: evolution-ews does not delete messages from the server (only hide them). I can verify it when view my mailbox through another mail client. When i delete messages using evolution-mapi, I see that messages was deleted from the server.
Thanks for a bug report. There is filled a similar upstream bug [1], thus I'm moving this there. Please see [1] for any further updates. If possible, please CC yourself there, in case upstream developers will have additional questions. [1] https://bugzilla.gnome.org/show_bug.cgi?id=664637
