How To Create Shared Mailboxes In Office 365

Today, I am writing about how to create shared mailboxes in Office 365. Shared mailboxes are helpful for a group of people in a corporation to monitor and send emails from a common account - for example, [email protected] or [email protected]. When we send the group replies to a message sent to the shared mailbox, the email looks like it was sent by the shared mailbox, not from the individual user.

Sign into Office 365 page with your account.
Go to Admin homepage and select the Admin tile, as shown below.

It will take us to the Admin center. Here, we need to select "Exchange" menu from left side admin center options.

Once we select the option, it will take us to the "Exchange admin center" page.
Here, we will find many options available in the left side pane. Select "recipients" then "shared" tab on the top of the page.

Now, on the above page, we need to select "+" button to create a shared mailbox.
We will get "new shared mailbox" wizard for creating new shared mailbox.

Feed below details on the available page

Display Name
Assigned name which will display as shared.
Email address
Enter the email address for the shared mailbox. It's required. Just enter the email address name and select domain from available dropdown.
Users
It will provide us details about which user can send and view created shared mailbox.

Once you are all done, click on "Save" button and wait till it gets created.
We will verify the same shared mailbox with assigned username which can view and send email.
Open Outlook and change the email account to created mailbox and send a test mail.

Use the "Exchange Management Shell" to create a shared mailbox. Users who are members of the security group will be granted the permissions to the mailbox.
