Discover what shared mailboxes in Microsoft 365 are, how they work, and their benefits for team collaboration. Learn how to set one up and best practices for efficient email management.
Why Effective Email Management Matters
Tired of important emails getting lost or missed in individual inboxes? If your team frequently struggles to keep up with group communication, shared mailboxes could be the game-changer you need. These collaborative email accounts streamline communication and make it easy for multiple team members to manage emails, ensuring nothing falls through the cracks.
In this guide, we’ll break down what shared mailboxes are, how they work, their key features, and the best practices for maximizing their potential.
What Are Shared Mailboxes in Microsoft 365 and Why Use Them?
A shared mailbox in Microsoft 365 is a collaborative email account that allows multiple users to send and receive emails from a common address, like “support@yourcompany.com” or “sales@yourcompany.com.” Unlike personal mailboxes, shared mailboxes are designed to improve team collaboration and simplify email management.
Here’s why they’re so useful:
- They allow team members to easily track and respond to emails.
- Shared calendars and contacts simplify scheduling and coordination.
- You can manage communication centrally without needing to switch between different platforms.
Example Use Cases:
- A customer support team uses a shared mailbox to respond to inquiries and ensure fast service.
- The sales department manages incoming leads and follows up as a coordinated effort.
- An HR team handles job applications and employee requests in one organized place.

Key Features of Shared Mailboxes
- Send as/Send on Behalf
- Send as: Users can send emails as the shared mailbox, making it appear as if the email came directly from “support@yourcompany.com.”
- Send on Behalf: Users can send emails on behalf of the shared mailbox. Recipients will see the email as coming from “User Name on behalf of Shared Mailbox Name.”
- Shared Calendar for Team Scheduling
- A shared mailbox includes a calendar that all members can access, making it easy to schedule meetings, track project deadlines, or manage team availability.
- Shared Contacts for Easy Access
- Store important contacts in one place, accessible to all team members, which helps improve efficiency when dealing with clients or vendors.
- Mobile Access
- Users can access shared mailboxes on their mobile devices through the Outlook app, making it simple to manage communication on the go.
How Shared Mailboxes Work in Microsoft 365
When you set up a shared mailbox in Microsoft 365, users don’t need to log in separately to access it. Instead, they use their own accounts and view the shared mailbox through their Outlook app.
Accessing Shared Mailboxes:
- Outlook Desktop App: The shared mailbox will appear automatically in the left navigation pane under the user’s personal mailbox.
- Outlook Web App: Users can switch to the shared mailbox by clicking their profile picture and selecting “Open another mailbox.”
- Mobile Devices: Users can add the shared mailbox to their Outlook app for on-the-go access.
Permissions Explained:
- Full Access: Allows users to open the shared mailbox and read, delete, and send emails. However, they can’t manage permissions.
- Send as: Users can send emails that appear to come directly from the shared mailbox.
- Send on Behalf: Users can send emails on behalf of the shared mailbox, showing the sender’s name alongside the shared mailbox name.

Benefits of Using Shared Mailboxes
- Improved Team Collaboration
- With multiple team members accessing the same mailbox, there’s less risk of missed messages. Team members can see which emails have been handled and who is responsible for follow-up, making collaboration seamless.
- Cost-Effective Solution
- Shared mailboxes don’t require additional Microsoft 365 licenses, provided they stay under 50 GB of storage. This makes them a budget-friendly way to manage group communication.
- Centralized Email Management
- Keep all relevant communication in one place, reducing the chaos of scattered emails and ensuring that high-priority messages get the attention they deserve.
- Consistent Communication for Your Brand
- Using a unified email address, like “sales@yourcompany.com,” ensures that your team maintains a consistent brand image when communicating with clients and customers.
- Shared Calendar for Scheduling
- Manage team events, project deadlines, and meeting schedules easily with the shared calendar feature. Everyone can stay updated and coordinate better.
How to Set Up a Shared Mailbox in Microsoft 365
Setting up a shared mailbox requires administrator access but is a straightforward process. Here’s how to do it:
- Go to the Microsoft 365 Admin Center
- Sign in with your admin account and navigate to the “Groups” section. Click on “Shared mailboxes” and then select “Add a shared mailbox.”
- Create and Name Your Shared Mailbox
- Enter the desired name and email address, such as “support@yourcompany.com” or “sales@yourcompany.com.” Click “Save” to create the mailbox.
- Assign Users and Set Permissions
- Add the team members who need access and assign the appropriate permissions (Full Access, Send as, or Send on Behalf). Save your changes.
- Configure Additional Settings (Optional)
- Customize settings like automatic replies, mailbox forwarding, or retention policies based on your organization’s needs.
Note: It may take a few minutes for the shared mailbox to appear in users’ Outlook apps after setup.
Best Practices for Managing Shared Mailboxes
- Establish Clear Usage Guidelines
- Define how the shared mailbox should be used. For example, create a process for assigning emails, marking messages as resolved, or categorizing them by priority.
- Use Categories or Flags for Organization
- Encourage team members to use color-coded categories or flags to organize emails and indicate their status. This helps prevent duplicate work and keeps the inbox tidy.
- Monitor and Clean Up Regularly
- Shared mailboxes can fill up quickly, so make it a habit to delete or archive old emails. If storage approaches the 50 GB limit, consider upgrading or using retention policies.
- Pro Tip: Don’t assume your data is fully protected. Learn why Google and Microsoft aren’t backing up your data and the steps you must take to keep your critical emails safe.
- Enable Notifications for Critical Messages
- Set up alerts for high-priority emails to ensure they’re addressed promptly. This is especially useful for teams that handle urgent customer requests.
- Track Usage and Performance
- Use Microsoft 365 reporting tools to monitor mailbox activity. This can help you identify inefficiencies or areas for improvement in your email management process.
