Strange problem with imported emails in Outlook

Hello.

I have a problem. I've been doingthe migrationof mailboxesfromone mail serverto Exchange2013 ( outlook .pst files) using New-MailboxImportRequest cmdlet.And after the migration, I get an strangeness -if I openany importedemail intoOutlook (2010, 2013 versions),thenin the"From:" fieldinstead of"John Doe <jdoe@blahblahblah.com>" i see just text "John Doe" without address.And the address here is nothidden,it doesn't exist.When trying to reply Outlook, of course, does not recognize the address. But, if i open same email in OWAthen the addressokay and i can reply. Upgrading to Exchange 2013 CU2 couldn't solve this problem.
