Minimum Requirement: iOS 7.0 or later
1) Start off by going to the app store for your phone. Search for and download OWA for iPhone. Make sure its Outlook Web App and not just Outlook. The Outlook app is for personal email and cannot be configured for GT email.
2) Once it’s installed start up the application and tap sign in.
3) Now you need to enter your GT email address and GT account password. For some users this may fail and you will need to enter the settings manually (see step 4).
4) The manual settings are as follows:
GT e-mail address: firstname.lastname@example.org for most users, or custom e-mail address
Password: GT password
Domain: Leave blank
Once all the fields (except domain) are populated, press sign in and your mailbox should appear.
