Plesk and Hosted Exchange

[MarioP]

Hi guys,

I recently updated to Plesk 9.3. I have a Microsoft Online Services account with 5 Exchange email addresses linked to one of the domains on the Plesk. The domain has been verified by Microsoft and communication between Exchange accounts @domain.co.uk is working correctly.

However, when I send an email from an IMAP account on the same domain to one of the Exchange accounts I get an error message saying: Could not send message to SMTP server. Check that you have access to send messages via the server and that all To/CC/BCC addresses are valid. Error: SMTP server rejected email. Returned 550 5.1.1. Receipient address rejected: User unknown in virtual mailbox table.

I need to know if there's any way to have these emails delivered to the propper service.

Any help will be much appreciated. Thanks!

IgorG thanks for the reply. I just changed the setting and now I just get a bounce back and the email never gets to the Exchange server. I also tried creating the same account on the Plesk but without a mailbox and with that, obviously, emails just disappear.

Any other suggestions?
