On your iPhone’s home screen, tap ‘Settings‘.
Navigate to ‘Mail‘, then ‘Contacts‘, and then ‘Calendars‘, tap the option for ‘Add Mail Account‘, and then tap ‘Microsoft Exchange‘. (Please note that only one Exchange ActiveSync account can be set up at once.)
Complete the following required fields:
- Email (your full email address)
- Domain name
- Username (without @domainname.com)
Once all of the information is entered, tap ‘Next’, and after a moment, the iPhone will ask for the server information. This is the URL to your webmail. For example, ‘mail.example.com’ (Please note that you do not need to include http:// when entering the server information.) and tap ‘Next’.
If your webmail does not support SSL, the following message will display: “Exchange account verification failed.”
Tap ‘Next’ and then tap ‘Save’. Edit the account you just added, and tap ‘Account Info‘, and then change “Use SSL” to “Off“.
The iPhone will display a list of collaboration items to sync with Exchange ActiveSync. Choose from the list and tap Done to initiate the first sync.
