Greetings! I've got working Ex 2010 deployment for about two months. Its Ex 2010 Eng Enterprise. Suddenly, about 3 days ago Ex started to corrupt cyrillic filenames in attachments. Does anyone know why this has happened? The strange this is that if I send attachment with digits or english letters in a filename, then the file is successfully delivered without alterring. But if there are even some letters in cyrilic then they are replaced with question marks (?). For example, if I send a file with the following name: some_cyr_letters.pdf (and some_cyr_letters is written in cyrillic), then exchange delivers it to the endpoint recepient with the following name: ????_???_???????.pdf. Moreover if a recepient is in the same org, co-worker for example, then even cyrillic filenames are delivered correctly. But if a recepient is outer e-mail address, yahoo or gmail for example, then filename becomes replaced with question marks. Please help!

It sounds like the necessary language pack hasn't been installed: http://technet.microsoft.com/en-us/library/dd298152.aspx --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi, I also think is a language pack issue. Could you please send an test email with three attachments, an English filename , an Arabic numbers filename and a cyrillic filename? If only the cyrillic filename changed, it should be.
