When a Microsoft Exchange Server 2007 user tries to send a message to a recipient who has a one-off FAX address, and there are certain language characters (for example, Arabic characters) in the address, a Non-Delivery Report (NDR) is generated that resembles the following:
From: Microsoft Exchange To: <FAX address that includes Arabic characters> Sent: <Date, Time> Subject: Undeliverable: <subject> Delivery has failed to these recipients or distribution lists: '<FAX address that includes Arabic characters>' The format of the recipient's e-mail address isn't valid. A valid address looks like this: firstname.lastname@example.org. Microsoft Exchange will not try to redeliver this message for you. Please check the e-mail address and try sending the message again, or provide the following diagnostic text to your system administrator. _____ Sent by Microsoft Exchange Server 2007 Diagnostic information for administrators: Generating server: <Exchange Server name> <FAX address that includes Arabic characters> #550 5.1.3 STOREDRV.Submit; invalid recipient address #FAX# <Original message headers>
In this scenario, Exchange Server 2007 did not support those languages that had characters that are larger than 0xFF in Unicode.
To resolve this problem, install Update Rollup 7 for Exchange Server 2007 Service Pack 1. For more information about Update Rollup 7 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic:
