We get ERROR D107 if we try to forward a message form search dialog, if the message is form a proxy-user.

We use GW 8.02 SP2 for Server and GW 8.02 SP2 HP3 Client.

Situation: User starts search (tools -> search), selects one or more proxy-user, starts seach.
If he tries to forward an e-mail of a proxy-user he gets the ERROR D107

Any ideas?

Thanks for the help
