           Summary: Moving/copying messages to folders causes redownload
                    of the entire folder [Exchange server]
           Product: Akonadi
           Version: 1.4.80
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: IMAP resource
        AssignedTo: ervin at kde.org
        ReportedBy: thiago at kde.org
                CC: vkrause at kde.org, kdepim-bugs at kde.org


Version:           1.4.80 (using Devel) 
OS:                Linux

If I copy or move an email to a different folder from KMail2 on my Exchange
2010 server (no UIDPLUS support), the IMAP resource proceeds to redownload
everything in that folder. There appears to be some faulty logic in
kdepim/runtime/resources/imap/retrieveitemstask.cpp in
RetrieveItemsTask::onFinalSelectDone.

If I apply the following patch to that file:
-    kDebug(5327) << "UIDNEXT check failed, refetching mailbox";
+    kDebug(5327) << "UIDNEXT check failed (old UIDNEXT =" << oldNextUid
+                 << "but current UIDNEXT =" << nextUid << "), refetching
mailbox";

I see in my debug output:

akonadi_imap_resource_0(12064)/kdepimlibs (kimap)
RetrieveItemsTask::onFinalSelectDone: UIDNEXT check failed (old UIDNEXT = 3012
but current UIDNEXT = 3013 ), refetching mailbox

The commands conversation with the server that was logged, relating to that
mailbox is:

[last SELECT before the copy]

S: * OK UIDVALIDITY value [ UIDVALIDITY 969  ]
S: * OK The next unique identifier value [ UIDNEXT 3013  ]
S: A000132 OK SELECT completed. [ READ-WRITE  ]

It's during the last section that the debug message is printed.

Reproducible: Always
