Many of our clients use Google Apps for Business as a back end for their company email. On a regular basis, I am asked how to add a Google Apps account to an iPhone or other iOS device. I have compiled the instructions below with some screen shots to guide you.
Step 1: Find and click the Settings icon on your home screen.
Step 2: Click Mail, Contacts, and Calendars.
Step 3: Click Add Account.
Step 4: Click Google.
Step 5: Enter your name, full email address, password, and whatever you’d like to use as a description or nickname for the account. Then click Next.
Step 6: Choose which items you would like to sync. In most cases it is fine to sync all 4 of the categories: Mail, Contacts, Calendars, and Notes. Then click Save.
That’s all there is to it. When you open the mail app on your device, you will see a new inbox for this account. If you chose to sync your contacts and calendars, they will show up in the corresponding apps.
