Hello,
I have Exchange Server 2010 SP3. All users can send and receive email via webmail.
Some users can not send and receive email via microsoft outlook. If they send email only stuck in outbox and there is no mail receive in their inbox. But another users cand send and receive mail via microsoft outlook correctly.
I have check queue in hub transport server and edge transport server, there is no problem i found.
I have check microsoft exchange mail submission service on mailbox server, and it's started.
How do i troubleshoot this problem? Please help me.
Thanks,
Suhud
