Evaluate Exchange Online Plan 1 and Plan 2 based on your family's mailbox size, archiving needs, and budget before setting up your DNS records.

Exchange Online offers enterprise-grade email features including shared mailboxes, distribution lists, multi-factor authentication (MFA), and robust spam filtering, which provide excellent security and flexibility for a custom family domain.

1
Evaluate Exchange Online Plan 1

Plan 1 offers 50 GB of mailbox storage per user, which is generally sufficient for standard family use, along with built-in archiving and calendar features.

2
Evaluate Exchange Online Plan 2

Plan 2 provides 100 GB of mailbox storage and unlimited archiving capabilities. Consider upgrading to this tier only if specific family members require extensive email retention.

3
Assign User Licenses

Purchase and assign the chosen license for each active user mailbox in the Microsoft 365 Admin Center. Shared mailboxes (up to 50 GB) do not require a separate license.

4
Update Domain DNS Records

Log into your domain registrar (e.g., GoDaddy), navigate to the DNS management page, and update your MX, TXT, and CNAME records to point to Microsoft's servers to activate email routing.

Frequently Asked Questions

Do I need to buy a license for a shared family mailbox in Exchange Online?

No, shared mailboxes up to 50 GB do not require an independent Exchange Online license. However, any user who needs to access the shared mailbox must have their own licensed Exchange Online account.

Can I use my custom GoDaddy domain with Exchange Online Plan 1?

Yes, Exchange Online fully supports custom domains registered through third-party registrars like GoDaddy. You simply need to verify domain ownership in the Microsoft 365 Admin Center and update the necessary MX and TXT DNS records.

Does Exchange Online Plan 1 include desktop Office applications like Word and Excel?

No, standalone Exchange Online plans only provide email and calendar services. If your family needs desktop applications, you must purchase a broader Microsoft 365 plan or use a free, highly compatible alternative suite like WPS Office.
