Microsoft 365 Shared Mailboxes for Small Businesses

Shared mailboxes help small businesses manage email addresses like info, support, billing, hiring, or office without tying important communication to one employee's personal mailbox.

Why this matters

If business email lives only in one person's mailbox, the company may lose visibility when that person is unavailable or leaves. Shared mailboxes help teams monitor important messages while keeping access easier to manage.

They can also support business continuity, department communication, and cleaner offboarding.

Common signs of the problem

• Customers email one employee instead of a business inbox.
• Former employees owned important email conversations.
• Multiple people share one password for a business email account.
• Team inbox access is not documented.
• Mailbox permissions are not reviewed regularly.

What to review first

1. Identify business email addresses that should be shared mailboxes.
2. Review who has access to each shared mailbox.
3. Remove access that is no longer needed.
4. Document mailbox owners and purpose.
5. Review send permissions and delegation.
6. Review shared mailbox use during offboarding.
7. Create a simple shared mailbox request process.
