Event ID 4089 - GroupWise 5.5 Migration

Hi,

I have multiples errors when I use the Exchange Migration
Wizard in a Groupwise 5.5 migration to Exchnage 5.5. All
the errors report the same event 4089 that is referent to
the groupwise attachment that the wizard can not migrate.

The attachment are other embedded messages with
attachments. If the attachments are direct to the message
no problem.

Anybody knows what can i do???

Thanks for the help!
