After you have created a shared mailbox, you'll want to configure some settings for the mailbox users, such as email forwarding and automatic replies. Later, you might want to change other settings, such as the mailbox name, members, or member permissions.
In the admin center, go to Teams & groups > Shared mailboxes.
Select the shared mailbox you want to edit, and then select Edit under Basic information.
Enter a new name for the shared mailbox.
Select Save.
In the admin center, go to Teams & groups > Shared mailboxes.
Select the shared mailbox you want to edit, and then select Edit under Email addresses.
Enter a new email address for the shared mailbox. If you want to change the primary email address, your mailbox must have more than one email alias.
Important
Email forwarding to recipients outside the organization doesn't prevent messages identified as spam, phishing, or malware from being forwarded. The recipient needs their own email security filter to identify and block these messages.
You do not need to assign a license to the shared mailbox in order to forward email that's sent to it. You can forward the messages to any valid email address or distribution list.
In the admin center, go to Teams & groups > Shared mailboxes.
Select the shared mailbox you want to edit, then select Edit under Email forwarding.
Select the checkbox to Forward all emails sent to this mailbox. Enter one email address to forward the messages to. It can be any valid email address. To forward to multiple addresses, you need to create a distribution group for the addresses, and then enter the name of the group in this box.
Select Save.
In the admin center, go to Teams & groups > Shared mailboxes.
Select the shared mailbox you want to edit, then select Edit under Automatic replies.
Select the checkbox to Send automatic replies to senders inside this organization.
Enter the replies you want to send to people inside or outside your organization. You can't add images, only text.
Select Save.
Allow everyone to see the Sent email (the replies)
By default, messages sent from the shared mailbox aren't saved to the Sent Items folder of the shared mailbox. Instead, they are saved to the Sent Items folder of the person who sent the message.
If you want to allow everyone to see the Sent email, in the admin center, edit the shared mailbox settings. Select Edit under Sent items. Select the options you want for sent items.
In the admin center, go to Teams & groups > Shared mailboxes.
Select the shared mailbox you want to edit, then select Edit under Email apps.
Select the checkboxes for all of the apps you want members to be able to use to access the shared mailbox.
Select Save.
