When launching Outlook and clicking through the setup wizard to create a new profile, Outlook auto-discovers the correct email alias. When establishing a connection it successfully checks network connectivity and successfully searches the email settings. When it attempts to logon to the mail server the error comes up.
"The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."
Clicking "Check Name" gives the error:
"The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."
The same result occurs with a manual setup.
We are running Exchange Server 2013. User workstations are running Outlook 2013 on Windows 7 Pro. All updates have been applied as of March 31, 2015.
All name changes have been made in AD and Exchange. Old aliases and new aliases are set in Exchange. Offline Address books are updated daily. The local profile and registry settings have been updated on the workstation and the user is successfully logging into the profile. The issue is only with Outlook 2013. User can access mail through OWA and ActiveSync on their mobile device.
Logging the user into another workstation and running the wizard returns the same results, which rules out the possible problem being with the workstation.
