Unicode (UTF-8) encoded messages are displayed incorrectly in Outlook after migrating from GroupWise to Exchange.
Special Characters (e.g. some french, spanish or german characters) do not come over as expected.
The PR_INTERNET_CPID property of the message in question is set incorrectly, so that the HTML body shows up in the wrong character set after the migration.
Fix available
The Development Team has fixed this in GroupWise Migrator version 3.5.1.54. Please contact a Quest Support Representative if you experience above behavior.
