In reference to an older post. Currently using IIM bundled with IMail.
Had to recover from a server issue. IIM is working but now when users message offline users, they receive a kickback message "User (firstname.lastname@example.org
) is not a valid user".
I notice that when an offline user is messaged, they do not receive messaged in their "Missed Conversations."
UPDATE: When sending a message to an offline user, the sender receives the message, but when the offline user signs on again, receives the offline message in Recent Conversations, not Missed Conversations.
