utf-8 subject encoding

Hello
I’m Russian speaking. 
Mail server is Exchange 2007, with the last version of emclient.
The problem is in message subject. Sometimes I get smth like this:
=?utf-8?q?=d0=b7=d0=b0… 
I’m not sure, but it’s possibly relates to special characters in message subject.
Also I have the same problem with file names of attached files. 
Could you advice any solution?
