Exchange Online Archiving for Exchange Server — Pricing, Plans & What’s Included

Exchange Online Archiving for Exchange Server includes a Microsoft-hosted archive mailbox for a licensed user whose primary mailbox remains on Exchange Server. It is licensed per user because each archive mailbox is assigned to an individual user who needs cloud-based archiving.

No, Exchange Online Archiving for Exchange Server does not provide a primary Exchange Online mailbox because it is an add-on archive service for users with primary mailboxes on Exchange Server. If users need cloud primary mailboxes, choose an Exchange Online or Microsoft 365 plan instead.

License each user who needs an online archive mailbox because Exchange Online Archiving for Exchange Server is sold per user. Do not license users who do not need Microsoft-hosted archive mailboxes unless another compliance or retention requirement makes that necessary.

Commercial customers can buy Exchange Online Archiving for Exchange Server with a monthly commitment billed monthly, an annual commitment paid upfront, or an annual commitment billed monthly.

Choose Exchange Online Archiving for Exchange Server when users keep primary mailboxes on Exchange Server and only need Microsoft-hosted archive mailboxes. Choose Exchange Online or Microsoft 365 instead when users need primary cloud mailboxes, Microsoft 365 apps, Teams, or a broader productivity bundle.

No, Exchange Online Archiving for Exchange Server does not include Microsoft 365 apps or Teams because it is an archiving add-on, not a productivity suite. Businesses that need desktop apps, web apps, Teams, or bundled collaboration services should evaluate Microsoft 365 or Office plans separately.

No, Exchange Online Archiving for Exchange Server does not include Microsoft 365 Copilot because it is only an archive-mailbox add-on. Copilot eligibility depends on separate Microsoft 365 licensing and prerequisites, so confirm the user’s base plan before buying Copilot.

The exact supported Exchange Server version and hybrid configuration requirements should be confirmed before deployment because compatibility depends on the customer environment.

Confirm the migration approach with IT Partner before starting because PST import, retention settings, and user access need to be planned carefully.

Microsoft service limits can vary by plan, tenant configuration, and current service terms.

Exchange Online Archiving for Exchange Server can be part of a retention and compliance strategy, but exact retention, hold, eDiscovery, and Microsoft Purview capabilities must be confirmed for the tenant, Exchange Server version, and licensing stack. Do not assume every compliance feature is included solely because the archive mailbox is licensed.

No, Exchange Online Archiving for Exchange Server should not be treated as a dedicated backup, journaling, or third-party compliance-supervision product because it is an archive-mailbox add-on. If the business needs immutable backup, journaling, review workflows, or regulated supervision, validate separate Microsoft or third-party solutions.

Security outcomes still depend on tenant configuration, identity controls, retention policies, and administrator practices, so confirm the required controls before deployment.

GCC and GCC High are not interchangeable with Commercial purchasing, and residency or sovereignty requirements should be reviewed with IT Partner before selecting a government cloud option.

Nonprofit grants, charity pricing, and education licensing are separate Microsoft programs and should be confirmed before purchase.

A CSP transfer to IT Partner should be a zero-downtime licensing and billing administration change because the Microsoft tenant and archive mailboxes are not moved. IT Partner should verify the current subscription, commitment term, and transfer path before initiating the change.

No, a properly handled CSP transfer should not change archive data or user mailboxes because it changes the partner relationship rather than migrating the service. The same Microsoft catalog SKU and matching commitment option can be used, but current catalog terms and any partner-specific charges should be confirmed.

Adding seats is generally possible during an active subscription because additional users may need archive mailboxes after the initial purchase. Reducing seats or canceling seats depends on the selected commitment term and Microsoft CSP rules, so confirm the change window before choosing monthly or annual commitment.

At renewal, Exchange Online Archiving for Exchange Server normally continues under the selected commitment unless the subscription is changed or canceled according to CSP rules. Cancellation and non-renewal can affect access to archive mailboxes, so export, retention, and compliance requirements should be reviewed before ending the subscription.
