Microsoft Exchange 2016 on 2012 R2 / IMAP synchro problem

Good day.

I recently installed Microsoft Exchange 2016 over Windows Server 2012 R2.

IMAP4 , POP3 services are on.

I created an email account on Exchange and i tried to move my 5000 emails from local pst to the Exchange Account over IMAP.

(Windows 10 Professional x64, Microsoft Outlook 2013 x32 , one account local and a second account with IMAP to this Exchange Server.)

I copied the files from Inbox of my local account to IMAP account (copy function of outlook 2013). The target files appeared correctly to the IMAP view of Outlook Client, but the Microsoft Exchange Server 2016 stopped to synchronize the files, with the "Microsoft Exchange Notification Broker" Service stopped. I tried to restart the service and for some seconds, some emails synchronized and then the same service stopped. And this goes on all over again. This event make the transfer of 5000 emails impossible. Any ideas ???
