Using Exchange 2003 with Outlook 2007 clients. I have a User who sends mail to an external AOL mailbox/recipient. When the AOL user replies, he gets a OWA logon prompt for my OWA domain name. Why would this happen? Thank you.

Please check if the issue happens for other internal recipients via outlook and OWA Please check if the issue happens to all the external recipients’ clients Please check if the issue happens when other internal senders deliver the message externally The tests above will help you to narrow down the cause and troubleshoot the issuePlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
