M365 Email Building Blocks
SHHA uses four distinct patterns for email addresses in Microsoft 365. Before requesting any new address, understand which pattern fits your need. This page is the reference for anyone planning new committees, roles, or special-purpose addresses.
The Four Patterns at a Glance
| Pattern | What it is | Example | When to use it |
|---|---|---|---|
Personal mailbox; first.last@sandiahomeowners.org |
A licensed M365 account owned by one person. Has its own login, calendar, OneDrive, etc. | anna.smith@sandiahomeowners.org |
Office staff and IT admins who need to log in to Microsoft 365 and perform admin tasks. Costs a license. |
Shared mailbox; role@sandiahomeowners.org |
A mailbox tied to a position, not a person. Multiple licensed users can open it from their own account. Retains full email history across holders. | president@sandiahomeowners.org; cscchair@sandiahomeowners.org |
Only one of SHHA's six officer roles: President, Vice President, Secretary, Treasurer, ACC Chair, or CSC Chair. Each officer receives Full Access and Send As through the officer's own licensed account. |
Mailing list (Microsoft Group); committee@sandiahomeowners.org |
A distribution group. Email sent to the address is delivered to every current member — including external guests who have no M365 license. | csc@sandiahomeowners.org; shha-all@sandiahomeowners.org |
Any group of people who need to receive the same email. Most committees have one. No license cost for external members. |
| Alias; (additional address on an existing mailbox or group) | An extra email address that delivers to an existing mailbox or group. Not a separate mailbox — just an alternative address for the same destination. | wildfire@sandiahomeowners.org → delivers to the ESC group or a specific shared mailbox |
One-off or special-purpose addresses (task forces, events, topical inboxes) where you do not need a separate mailbox with its own history. Use when you want a memorable address that maps to something that already exists. |
Which Pattern Do I Need?
Walk through these questions when planning a new email address:
- Does one specific person need to log in to M365 and perform admin tasks?
- Yes → Personal mailbox (requires a license; talk to IT admin)
- No → continue
- Does the address need its own persistent inbox that survives personnel changes?
- Yes → Shared mailbox
- No → continue
- Does the address need to deliver to a group of people?
- Yes → Mailing list (Microsoft Group)
- No → continue
- Do you just need a convenient address that routes to an existing mailbox or group?
- Yes → Alias on the appropriate existing mailbox or group
- No → talk to IT admin to figure out the right approach
Combining Patterns
For a committee or task force, the normal setup is:
| What | Pattern | Typical result |
|---|---|---|
| Committee mailing list | Microsoft Group | One address that reaches all current members, including external volunteers |
| Committee documents | SharePoint site | One group-owned Documents library for the committee record |
| Friendly alias (optional) | Alias on the group | An additional memorable address that routes to the group |
| Officer role inbox (only when applicable) | Shared mailbox | One of the six officer addresses; never a general chair or task-force mailbox |
You generally do not need to create personal mailboxes for volunteers. External volunteers receive group email at their personal addresses (Gmail, Yahoo, etc.) and use SharePoint in a browser.
Archive Rule
Every mailing list (Microsoft Group) must include as a member. This is the archive account that preserves all committee email for continuity and records. It is not monitored for support.itadmin@sandiahomeowners.admin@sandiahomeowners.org
Cost Summary
| Pattern | License cost |
|---|---|
| Personal mailbox | Requires a paid M365 license |
| Shared mailbox | Free (up to 50 GB; no license unless it exceeds the limit) |
| Mailing list (Group) | Free |
| Alias | Free (added to an existing mailbox or group) |
