I installed last night new exchange 2013 cu2 server to Exhange 2010 sp3 organization and found one mystery problem.
If i send email to outside from my organization and message body includes ä or ö letters they are converted to ? character.
Sending same email to user inside organization everything is working normaly. If i add ä or ö letter also to subject, then message looks normaly also sending to outside user.
Have anyone any ideas how to resolve this problem?
