After migrating from Exchange 2007 to 2013, Outlook cannot connect

We migrated from Exchange 2007 to 2010 and now when I try to create a new profile in Outlook 2010 I receive the following message: "Outlook cannot log on. Verify you are connected to the network and are using the proper server and mailbox name."

I have quadruple checked my autodiscover entries in DNS and changed Outlook anywhere between Basic, Negotiate, and NTLM without any success. How can I resolve this?

Thank you

Have you opened all necessary ports? There are 2 custom ports which must be open between client machine and the CAS servers. Those ports are defined in registry or a config file based on the version of outlook you use.

Yes, I've turned off the firewall as well for testing

Now instead of giving me the error message, I'm stuck in an endless loop of Outlook 2010 asking for my username and password when I create a profile and it will not accept the correct information.

Please try to close outlook (or Kill it).

Delete the current profile and try this:

-  Open a browser and navigate to your "externa/internal" hostname for the Exchange server (https://webmail.domain.com/owa) try to log in with a valid username and password. If that works, go to next step, if not your DNS settings are not set properly.

-  Open outlook, it should detect the current user's info and create the account, it may ask for the password to access the server/mailbox, depending on your settings you may need to enter it on "Domain\username" format, then the password and choose to remember this credentials before hitting enter or clicking the OK button.

Good Luck!

I found that the problem was caused by some Outlook Anywhere settings on the old server that were transferred to the new server. When the previous company setup Exchange 2007 they had set the Outlook Anywhere address to "mail.domain.com"  so when the settings transferred over and users tried to connect to the new server, Exchange 2013 told them to try to connect to mail.domain.com. I had to change this manually for each user after changing the Outlook Anywhere settings to the correct server name.
