If you followed the security recomendations in Office 365 and disabled the ability for users to consent for apps, iPhone users will be facing the message “iOS accounts needs permission to access resources in your organization” during native mail account setup for Exchange Online.
I had this situation and find some articles to solve the problem. I would like to give you a short summary of these articels.
Few weeks ago I had to implement Microsoft Exchange Online for a customer who didn’t used Exchange in the past. For a simple user management, I decided to install and configure Azure AD Connect. So the user accounts from local Active Directory will be synchronized to Azure AD.
There are several advantages of this scenario:
you have a single point for user management, your local Active Directory
if configured, user passwords (or better to say password hash values) are automatically synchronized to Azure AD
the user has a Single-Sign-On Experience for Office 365 services
Office 365 license assignment based on local AD groups
After setting up Azure AD Connect and enabling all users for Exchange Online, I started to configure some Exchange settings: configure distribution lists, shared mailboxes and second mail addresses. But wait, what’s that? After submitting the change and error message pops-up:
What da hack? After some research in the web and reading several blog entries, it was clear: When using AAD Connect and synchronized accounts in Office 365, you have to install an on-premises Exchange Management server for changing some Exchange Online settings. Even you don’t have an on-premises Exchange server installed yet. Very disappointing and frustating. That’s why a customer decides to use cloud service: they wan’t have to install and maintain the system on-premises.
