We have a user on a Windows 7 (Pro) laptop using Outlook 2010. He has left his former employer, but still has an Exchange account configured from that employer.
I created a new account to POP email from a different email address. Outlook receives messages from the POP server and when I reply to thoe messages they are sent. When I compose a new message (ie: not a reply to something in the inbox) the message does not send. Outlook says, "The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."
I've changed the default account from the Exchange account to the POP account. Still cannot send new messages. I've changed the default data file from the ost (Exchange account) to the pst (POP account). Still cannot send new messages. I've setup a send/receive group that contains only the POP account. The send/receive process completes successfully, but if I create a new mail I get the exchange connection problem again.
Anyone know what's going on here? and more importantly how to resolve this problem?
