we repeatedly see the following problem:

User sends email from his mobile; recipient sees the email with completely
different sender (another GroupWise user). That other Groupwise user sees
the email in his/her outbox. In addition the sender sees the address book of
the other user in Mobility Service.

Reboot of the Mobility Service server solves the problem temporarily,
restart of the deamons does not.

Especially the fact, that users might read outgoing mail from other users,
is a serious problem.

Anybody has seen such problems? Any idea what the reason for that confusion
