Ross Smith IV Ivan54 Thank you both for your feedback, after more testing it appears that if you have ANY (even a generic shared mailbox) Exchange account configured in iOS under Settings-Passwords & Accounts (EAS), then you will be unable to choose "Save Contacts" in Outlook for iOS, and you will then get an iCloud error about not having an iCloud account configured (assuming you actually don't). However, if you first configure "Save Contacts" in Outlook for iOS without having an EAS profile configured, then that will be successful. However, the big downside to this that I see is that, although I am aware and ok with this being a one-way sync to the phone, I don't see anyway to create or modify any of the user's contacts from within the Outlook for iOS app, which would be quite a burden on the user to require that they do all their contact management in Outlook/OWA. Not only is there no option to create a new field in an existing contact, but there also is no add contact button in the app. Is there something I'm missing here? I thought since there is a one-way sync that the suggested contact mgmt process would be to use the Outlook for iOS instead of the native contacts app, but these features seem to not be available now.
