Manage Email apps & mobile devices settings of a mailbox

This article talks about on how to Manage Email apps & mobile devices settings of a mailbox

Email apps & mobile devices settings

‎Email apps & mobile devices settings of a mailbox will help us to manage attributes like Outlook on the web, Outlook desktop (MAPI), Exchange web services, Mobile (Exchange ActiveSync), IMAP, POP3‎ etc.

Lets manage Email apps & mobile devices settings step by step

Open Exchange online admin center : https://admin.cloud.microsoft/exchange?#/mailboxes/

Navigate to EXO–> Home –> Mailboxes–> manage mailboxes–> select the mailbox whose ‎Email apps & mobile devices settings needs to be set

Now click on Manage settings for email apps

you will be able to turn on and off settings like MAPI, EWS, Exchange ActiveSync, IMAP and POP3

MAPI is a Microsoft set of functions enabling Windows applications to create, transfer, and manage email messages and data. It allows email clients like Outlook to interact closely with Exchange servers for advanced functionality, including handling calendars, contacts, and folder synchronization, rather than just sending mail

EWS is a cross-platform API created by Microsoft that enables applications to access, create, modify, and manage mailbox items—such as email, calendars, and contacts—within Microsoft Exchange Server (2007 onwards) and Exchange Online/Office 365. It allows developers to integrate Outlook data with other systems using SOAP-based XML messages over HTTP

Exchange ActiveSync is a Microsoft synchronization protocol designed to sync mailbox data—email, calendar, contacts, and tasks—between mobile devices and Exchange Server in real-time. It uses “Direct Push” technology over HTTPS for secure, efficient communication, allowing users to access data on low-bandwidth networks, both online and offline

IMAP is a standard email protocol that allows you to access and sync your emails across multiple devices (phone, laptop, tablet) by storing them on a central mail server. When you read, move, or delete an email via IMAP, that action is reflected instantly across all your connected devices

POP3 is a standard internet protocol used to retrieve emails from a mail server to a single local client, such as Microsoft Outlook. It downloads messages—typically deleting them from the server afterward—allowing for offline access

Outlook on the web is a browser-based version of Microsoft Outlook, allowing users to access email, calendars, contacts, and tasks via an internet browser without installing software. It is the primary interface for Microsoft 365 and Exchange Online, providing a similar experience to the desktop app for work, school, and personal accounts

Outlook web app mailbox policy can be set using a PowerShell command

Get-OwaMailboxPolicy -Identity mailbox | Format-List

Name                                                 : OwaMailboxPolicy-Default
