If you want Outlook and i. Phone to see the same data, though, you will be using Exchange Active. Sync from the i, and os side. Outlook is an email client for PCs and Macs. When you set up an Exchange account on an i. OS device, it uses Exchange Active, and sync.
Our goal: Allow users with personally owned i. OS devices to be able to use both Outlook for i. OS and the native mail app to access work email., i OS devices are required to be at i. OS version 12.0 at least., exchange active Sync will be turned off completely eventually.
Within the Microsoft 365 or Office 365-based architecture, Outlook for i. OS and Android uses the native Microsoft sync technology for data synchronization that is protected by a TLS-secured connection end-to-end, between Microsoft 365 or Office 365 and the app.
Outlook for i. OS and Android establishes a connection to Exchange Online and issues a provisioning request that includes the user’s access token (AT1) and the on-premises Active, and sync endpoint.
What is Exchange ActiveSync and why do I need It?
Microsoft recommends Exchange Active. Sync for managing the mobile devices that are used to access Exchange mailboxes in your on-premises environment., exchange active Sync is a Microsoft Exchange synchronization protocol that lets mobile phones access an organization’s information on a server that’s running Microsoft Exchange.
Does ActiveSync work with iOS devices with a pin?
, i OS devices are shipped with built-in encryption, which Outlook uses once the passcode is enabled to encrypt all the data Outlook stores locally on the i, and os device., therefore, i OS devices with a PIN are encrypted whether or not this is required by an Active, and sync policy.
Why can’t I send and receive emails with ActiveSync disabled?
When an Exchange Online mailbox has the Active. Sync protocol disabled, you may find that the Outlook app for i. OS and Android mobile devices is still able to connect to the mailbox to send and receive emails. The reason for this is the architecture of the Outlook app and the infrastructure it connects to.
