RE: On my new DELL Inspiron 15. cannot install my Exchange account in Outlook 2007
I just now see your mail and I am very late but I resolved the issue.
What did it was the following :
I logged in to Microsoft Office 365 on the web and via Settings you have an option to have your specific PC checked whether al relevant files are present.
In my case two files were missing and they were installed. After this the problem was solved.
I found the solution on Internet.
I am on vacation now, if you have more questions let me know and I can give you more details.
