There are many different types of email accounts you can add to Outlook, including Office 365, Gmail, Yahoo, iCloud, and Exchange accounts.
Some third-party email providers, like Gmail, Yahoo, and iCloud, require you to change some settings on their websites before you can add these accounts to Outlook.
These steps are the same whether you’re adding your first email account or additional email accounts to Outlook.
Select File > Add Account.
What you see next depends on your version of Outlook:
For Outlook for Office 365 and Outlook 2016
Enter your email address and click Connect
For Outlook 2013 and Outlook 2010
Enter your name, email address, and password, and click Next.
If prompted, enter your password again, then select OK > Finish to start using your email account in Outlook.
