Hi @Jim
For better research, please provide more details about this case:
Do other users in your organization have the same problem?
What type of account are you adding to your account (POP/IMAP/Exchange)?
Are you using Outlook for Mac?
According to the error message, this issue occurs because the Autodiscover process that's used by Outlook receives an unexpected result from a third-party web server when it performs the root domain lookup. More information, see: Something went wrong and Outlook couldn't set up your account - Microsoft Support.
Also, please try reconfiguring your account from the control panel. Control panel>Mail>Show Profiles…>Add…>type the name of your new profile>click OK>Configure the account according to your account type.
