Office365 – Creating a New Shared Mailbox

Creating a shared mailbox is simple with Office 365. Follow the step-by-step below, for the simplified process.

Per Microsoft – 

Shared mailboxes make it easy for a specific group of people to monitor and send email from a common account, like public email addresses, such as or When a person in the group replies to a message sent to the shared mailbox, the email appears to be from the shared mailbox, not from the individual user. 

Shared mailboxes are a great way to handle customer email queries because several people in your organization can share the responsibility of monitoring the mailbox and responding to queries. Your customer queries get quicker answers, and related emails are all stored in one mailbox. 

A shared mailbox doesn’t have its own user name and password. You can’t log into a shared mailbox directly using Outlook or Outlook Web App. You must first be granted permissions to the shared mailbox, and then you access it using Outlook or Outlook Web App. You don’t need to assign licenses to shared mailboxes, except when they are over their storage quota of 10 gigabytes (GB).
