Unable to find mapping for MIME character set 'ISO 8859 15' (4300923)

Unable to find mapping for MIME character set 'ISO 8859 15'

The following entry in found in the log file:

Unable to find mapping for MIME character set 'iso-8859-15. At first look, it appears that the message was not migrated.

This appears for various reasons, including

• Western European Characters in the body
• Internet URLs which may contain Western European language text

This is caused by the relavant codepage not being installed on the Migration console

RESOLUTION

The code is calling a system function GetCharsetInfo to find out more about a character set identified as “ISO-8859-15”.

The code pages a given system knows about are listed in HKey_Classes_Root\MIME\Database

If there is no mapping for “ISO-8859-15” in that registry, then NME will fall back to a default character set mapping.

Note that this is a Warning, and not an Error. If you are not seeing a bad character set mapping (if the differences between the recent ISO-8859-15 and the default 8859-1 are not causing problems) than this is just a warning to ignore. Most of the Warnings you see in the log files are safe to ignore. However, please ensure that the message is migrated properly by checking the Exchange Mailbox.
