            Bug ID: 338967
           Summary: Communication with exchange server breaks down after
                    initial sync
           Product: Akonadi
           Version: 1.13.0
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: IMAP resource
          Assignee: chrigi_1 at fastmail.fm

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.

Reproducible: Always
