Debian updated recently to KDE 4.14 (from KDE 4.13) and during that time also updated akonadi to 1.13 (from 1.12.1). After this update the communication with exchange servers (provided by hostedexchange.com) seems to be broken. Sometimes I get new messages after the restart of the system (or akonadi) but during a normal run (even when trying to sync a folder) I cannot get new messages at all. I would also say that it downloads all my messages again after a system start (at least this is what happened right now and a co-worker also told me that he sees this all the time). Also changing the state of a mail (read -> unread) doesn't seem to change it on the server. The account is a disconnected imap and I can see all changes on my imap folder in akonadiconsole but not on the server. The only communication with the server is following (even trying to get new messages/change messages/....):
SERVER: * OK The Microsoft Exchange IMAP4 service is ready.
CLIENT: A000001 AUTHENTICATE PLAIN
SERVER: +
CLIENT: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
SERVER: A000001 OK AUTHENTICATE completed.
CLIENT: A000002 CAPABILITY
SERVER: * CAPABILITY IMAP4 IMAP4rev1 AUTH=NTLM AUTH=GSSAPI AUTH=PLAIN STARTTLS
SERVER: CHILDREN IDLE NAMESPACE LITERAL+
SERVER: A000002 OK CAPABILITY completed.
CLIENT: A000003 NAMESPACE
SERVER: * NAMESPACE (("" "/")) NIL NIL
SERVER: A000003 OK NAMESPACE completed.
and after a while the server just disconnects the client with a TCP reset.
Any recommendations what I should try? Can I gather more informations to help debugging?
Also pressing the "Synchronize Folder" in akonadi for the INBOX of this account, or check mail in kmail2 for this account, or "Update Folder" on this account's INBOX in kmail2 doesn't create any output in the akonadiconsole debug output. As said before, also no new messages are exchanged with the server of TCP when doing that.
