Application developers who have built apps that send, read, or otherwise process email using these protocols will be able to keep the same protocol, but need to implement secure, Modern authentication experiences for their users. This functionality is built on top of Microsoft Identity platform v2.0 and supports access to Microsoft 365 email accounts.
Administrators who still use the old remote PowerShell connection method or the older Exchange Online Remote PowerShell Module (V1), are encouraged to begin using the Exchange Online PowerShell module as soon as possible. These older connection methods will eventually be retired, either through Basic authentication disablement or the end of support.
Do not confuse the fact that PowerShell requires Basic authentication enabled for WinRM (on the local machine where the session is run from). The username/password isn't sent to the service using Basic, but the Basic Auth header is required to send the session's OAuth token, because the WinRM client doesn't support OAuth. We are working on this problem and will have more to announce in the future. Just know that enabling Basic on WinRM is not using Basic to authenticate to the service. For more information, see Exchange Online PowerShell: Turn on Basic authentication in WinRM.

If you want to monitor the email from your primary mailbox and the shared mailbox at the same time, use this method. In addition, after you complete this task, the shared mailbox and its folders are displayed in the left navigation pane each time you open Outlook Web App.
Type the email address of the other mailbox that you want to open and then select Open. Or, start typing and then select Search contacts and directory to find the mailbox you want to open. Select the shared mailbox you want to open, and then select Open. Another Outlook Web App session opens in a separate window, allowing access to the other mailbox.
Select More , and then select Show From. This option shows you that the people who receive the email message will see that it comes from the shared mailbox and not from your own email account.
Note: The first time you use a shared mailbox to send an email, you won't see the name of the shared mailbox account in the Show From drop-down. For your first-time use, delete your name, type the name of the shared mailbox in place of your name, and then send the message. In the future, the name of the shared mailbox will display in the drop-down next to Show From, and you can select it.
Shared mailboxes are used when multiple people need access to the same mailbox, such as a company information or support email address, reception desk, or other function that might be shared by multiple people.
Users with permissions to the group mailbox can send as or send on behalf of the mailbox email address if the administrator has given that user permissions to do that. This is particularly useful for help and support mailboxes because users can send emails from "Contoso Support" or "Building A Reception Desk."
Encryption: You can't encrypt email sent from a shared mailbox. This is because a shared mailbox does not have its own security context (username/password) so it cannot be assigned a key. If more than one person is a member, and they send/receive emails they encrypted with their own keys, other members might be able to read the email and others might not, depending which public key the email was encrypted with.
Subscription requirements: To create a shared mailbox, you need to subscribe to a Microsoft 365 for business plan that includes email (the Exchange Online service). The Microsoft 365 Apps for business subscription doesn't include email. Microsoft 365 Business Standard does include email.
Multi-Geo In a multi-geo environment, shared mailboxes need to be licensed the same way a user mailbox is licensed. Note that cross-geo mailbox auditing is not supported. For example, if a user is assigned permissions to access a shared mailbox in a different geo location, mailbox actions performed by that user are not logged in the mailbox audit log of the shared mailbox.
To access a shared mailbox, a user must have an Exchange Online license, but the shared mailbox doesn't require a separate license. Every shared mailbox has a corresponding user account. Notice how you weren't asked to provide a password when you created the shared mailbox? The account has a password, but it's system-generated (unknown). You shouldn't use the account to log in to the shared mailbox. Without a license, shared mailboxes are limited to 50 GB. To increase the size limit to 100 GB, the shared mailbox must be assigned an Exchange Online Plan 2 license. The Exchange Online Plan 1 license with an Exchange Online Archiving add-on license will only increase the size of the archive mailbox. This will also let you enable auto-expanding archiving for additional archive storage capacity. Similarly, if you want to place a shared mailbox on litigation hold, the shared mailbox must have an Exchange Online Plan 2 license or an Exchange Online Plan 1 license with an Exchange Online Archiving add-on license. If you want to apply advanced features such as Microsoft Defender for Office 365, eDiscovery (Premium), or retention policies, the shared mailbox must be licensed for those features.
Office 365 notification MC181641 posted on June 5 includes the good news that Outlook mobile (iOS and Android) will soon support connections to Exchange Online shared mailboxes. This will remove the need for the IMAP4 connection currently used as a workaround to access shared mailboxes. Apart from the general kludginess of the IMAP4 workaround, if you log onto a shared mailbox with IMAP4., that mailbox should technically have an Office 365 license.
In other words, expect to see shared mailbox support appear in July 2019. That is, if support for the Microsoft Sync Technology is deployed to your Office 365 tenant. To check, look at the settings for your account (Figure 1), or use the PowerShell script in this article.
Microsoft Sync Technology is the new connection protocol for Outlook mobile clients that Microsoft has deployed to Outlook.com and the Government Cloud (GCC) and is now rolling out to commercial tenants. Hopefully, the advent of shared mailbox support serves as a spur for Microsoft to complete the deployment of the new sync technology.
it does not make me happy, it just makes me less bloodfirsty.seriously microsoft needed over a decade of mobile devices to add shared mailbox supportand no the imap method isnt a viable option at all
Microsoft Outlook is the only university-supported email client and is highly recommended for accessing your University of Colorado Denver | Anschutz Medical Campus email. In addition, OIT recommends installing the O365 Outlook app on your mobile device from the iOS and Android App store. Once you add the Outlook app to your phone, you can go to Settings and add other personal accounts such as Gmail. 2b1af7f3a8
