Hello all! So we have a new Exchange 2013 install with a few users. Everything was working fine except for Outlook which could not send email. When clicking on the send/receive button an error came up saying that it could not connect, even though the bottom right of the window said that it was connected.
After fooling around with the outlook anywhere settings I was able to get it working. Before long the connection to Exchange dropped and asked for a username and password. Now it doesn't accept the username and password and doesn't give an error. When connecting via OWA everything works fine.
So I went to control panel, clicked on the mail icon and deleted the exchange server account and tried to add it again. Unfortunately I cannot add it. It asks for the username and password as part of the setup but will not accept it even though I know that the credentials are correct. Again OWA works fine.
Here are some other things that I did but not sure if it caused this problem: Changed passwords and used an exchange cmdlet to configure email forwarding for a couple of accounts (which didn't work). All this was just before my authentication issues began. It seems as though Outlook is not communicating with the Exchange server even though I can login to OWA using the FQDN of Exchange.
Any thoughts???
