I had duplicated emails in my first attempt (c. 2011) to move to Kmail2.
This was on a POP3 account.  When I deleted the duplicates, more would be
created.  I did not have the full semantic KDEPIM enchilada enabled and
I was running sqlite3, which the KDE devs advised against (unable to
manage multithreaded operations that mysql/postgresql could do with
ease).  At the time I blamed sqlite as the cause of this, but I may have
been wrong if you are also observing the same.

More recently (c. 2013/4) I tried again to setup Kmail2, but using IMAP4
and mysql.  Small IMAP4 accounts with a couple of thousand messages work
fine.  Large IMAP4 accounts with 120k messages or more, work like a pig,
unless you have FTTP and some octa-core beast to run your desktop on.

HEALTH WARNING: This can potentially delete ALL your messages, with the
same ease that it creates duplicates.  So, ensure that you have some
back up system, to safeguard loss of your email data.

If you open the akonadi console you should be able to clear the akonadi
cache.  This ought to follow with a re-indexing of your messages by
akonadi, hopefully without creating a duplicate of each message in your
Inbox folder.
