How to Add an Office 365 Email Account to the iOS Mail App

Microsoft’s latest rev of the Outlook for iOS app has promise, but I still find the iPhone’s built-in Mail App is easier to use and much better integrated into the iPhone  and iPad ecosystem of emails, calendars and contacts.

STEP 1:
Go to your device’s Settings, scroll down and tap Mail > Accounts >Add Account.

Device Settings > Mail

Add Account

STEP 2:
Select Exchange.

Choose Exchange

STEP 3:
Enter your Office 365 email address, password, and a description of your account. Tap Next.

NOTE: Your email address should be your Office 365 business account or school account. Such as @yourdomain.com, @domain.onmicrosoft.com, or @schoolname.edu.

Exchange Sign In

STEP 4:
If you’re prompted to enter server settings, enter the following and tap Next.

  • Email: your full email address.
  • Server: outlook.office365.com.
  • Username: your full email address.
  • Password: email account password.

STEP 5:
The Mail app may request certain permissions such as accessing your calendar and contacts. To agree, tap Yes.

Then choose the apps you want your email account to sync with your iOS device and tap Save.

STEP 6:
Now you’re all set to go!

Please note: When you first add the Outlook 365 account to the Mail App, depending on how man emails you have in your account, it may take 5-15 minutes to sync up and work properly.  You’ll know this because the list of emails may be complete, but clicking on any email, the contents will come up blank.   Don’t panic.  Just go off and have a cup of coffee and then try again later.
