Look at the list of mail groups in almost any organization and you will find a time capsule: "Admissions-2019," a list for a committee that disbanded, a shared mailbox that three former employees can still open. Mail groups are easy to create and rarely removed, and over time they become a quiet source of confusion and risk.
A little ownership and a regular review keep them under control. Here is how to tidy up and keep it that way.
Terms vary by platform, but the common types are:
Distribution lists, which send a message to a set of people. Replies come from individuals.
Shared mailboxes, which are inboxes several people can open, often used for addresses like admissions@ or billing@.
Group or team-based mailboxes, which combine email with shared files and conversations.
Aliases, which forward one address to another.
Knowing which you have matters, because each handles access, retention and licensing differently.
Information exposure. A shared mailbox may hold resident or family information that ex-employees or the wrong departments can still see.
Misdirected email. Messages sent to an old list reach people who should not receive them, or no one at all.
Missed messages. An unmonitored inbox with a public address means a family request or a vendor notice sits unread.
Compliance gaps. The HIPAA Security Rule expects access to protected health information to be limited and reviewed. A shared inbox with outdated members does not meet that expectation.
Clutter and cost. Some shared mailboxes need licenses or storage, and long lists make it harder to find the right one.
Ask IT or your provider for an export listing every distribution list and shared mailbox, including:
Name and email address
Type
Members and, for shared mailboxes, who has permission to send or open it
Owner, if one is recorded
Last activity date, if available
Every group needs a named owner, a real person with authority, not an IT account. The owner is responsible for:
Confirming the group's purpose
Approving membership changes
Reviewing membership periodically
Deciding when the group is no longer needed
If a group has no clear owner and no one will claim it, that is a strong sign it can be retired.
Work through the list:
Delete or archive groups with no recent activity, after a short notice period to confirm no one needs them.
Merge duplicates, such as "Billing" and "Business-Office."
Remove former employees and anyone who has changed roles.
Replace individual memberships with role-based ones where possible, so access follows the job.
Limit who can send to large lists, particularly those reaching all staff, to reduce spoofing and accidental reply-all storms.
Review external access. Decide whether outside senders can email an internal list.
Because shared mailboxes often hold sensitive messages, check who has access and at what level. Prefer shared mailboxes that users open through their own accounts over shared passwords, which make it impossible to know who did what. If a shared mailbox is receiving resident or family information, include it in your access reviews.
Prevent future sprawl:
Use a consistent naming convention, such as a department prefix.
Require a request that names the owner and purpose before a new group is created.
Set an expiration or review date for temporary project groups.
Twice a year is a reasonable rhythm. Send each owner a list of their groups and members, and ask them to confirm or correct. Tie the review into your onboarding and offboarding steps so departures trigger removal from groups automatically.
Email may be part of your business records, and legal or contractual requirements may apply. Before deleting a shared mailbox, ask whether its contents need to be retained or exported, and coordinate with your compliance officer or counsel.
