Issue: If you are using Outlook Web  Access (OWA) in Firefox and you send an attachment with foreign characters in the filename, the recipient may see some characters of the filename as question marks (?) when the message is received by their device. This is an issue with OWA and the Firefox browser.

Solution: If you use Internet Explorer, this issue does not occur. Also using Outlook does not present this problem. See the following link for more information:
