Email not being delivered - log shows delivered

Hi guys,lately i am getting a strange problem.

i have 2 users A & B using one mailbox-Sales with their own user id’s.

one userA sends an email to another userX

User B cannot see the email in the Sent Items list.

User A can see the email in Sent Items.

Log shows email was delivered to user X

User X complains mail not received, check X mailbox for sure mail not received.

User A forwards the email again, and now User B can see forwarded email in Sent Items & User X received the email

so what happened the first time

any ideas anyone - IBM has given up on my problems.

cheers

Avi
