I have weird problem, its probably somehting small but I can't figure out whats going wrong.
Our client has a server 2008 r2 running Exchange 2010, they where using pop3 accounts on the cliënt itself to get mails. Over the weekend I changed the mail delivery directly to the server, I edited the DNS settings on the webserver, opened the ports, edited all the passwords and tested the OWA setup, everything works fine, I can access the OWA internally and externally using the new passwords.
But no mails are getting into the mailboxes. when I use the message tracking results I can see my test mails arriving fine. But I can’t see them in the mailbox. When I try to create a new Exchange profile on a client pc in the domein, the autodetect settings work fine, but when I open outlook it asks for the username and password, I will not accept the correct credentials. But het old profile works fine (still connected to Exchange, does not prompt for password) but no mails are getting in the box?
