After installing the Office apps, you'll want set up Outlook to start using email, calendar, and contacts.
On the Windows Start menu, search for Outlook, and select it.
(If you're using a Mac, open Outlook from the toolbar or locate it using the Finder.)
If you've just installed Outlook, on the Welcome page, choose Next.
Choose File > Info > Add Account.
Enter your Office 365 email address and choose Connect.
Enter your password, select Remember my credentials, and choose OK.
Choose Set up Outlook Mobile on my phone, too if you want to install the Outlook Mobile app. Choose OK.
To make your new account the default Outlook account, choose File > Info > Account Settings > Account Settings, select your new account, and then choose Set as default.
On the Email tab, select your new account and choose Set as Default.
On the Data Files tab, select your new account, choose Set as Default, choose Yes when prompted, and then choose Close.
To start using email, calendar, and contacts on your computer, you need to set up Outlook.
Just search for Outlook on the Windows Start menu and select it.
If this is the first time you've used Outlook on this computer, you'll see this welcome message. But because we were previously using Outlook on this computer, we see our old email account.
To add our new Office 365 account, go to File, then Add Account.
Leave Email Account selected. Then enter your name as you would like it to appear in emails. Then your Office 365 email address and password. Then Next.
Wait for Outlook to set things up. Then enter your password again and choose Remember my credentials, then OK.
If you leave Set up Outlook Mobile selected, you'll be taken to that page next.
When prompted to restart Outlook, choose OK.
Open Outlook again, and now we see our new Office 365 email. And in our case, we also see our old email account that was previously added to Outlook.
To make the new Office 365 account the default in Outlook, go to File and open Account Settings.
Select your new account, and choose Set as Default for email.
Then on the Data Files tab, set your account as the default, then Yes to changing the default data file, and Close.
You'll see your new Office 365 email as the default email account now. And you're ready to stay on top of email, calendars, and contacts in Outlook.
If you have a previous email account like this, you can still use it, or import that information into Office 365.
