The simplest way to migrate, assess, and govern Microsoft 365

Yes, ShareGate supports tenant-to-tenant Exchange Online mailbox migrations for primary mailboxes, Microsoft 365 Group mailboxes, and in-place archive mailboxes.

No, ShareGate Migrate Pro and Enterprise include Exchange Online mailbox migration as part of the same platform used to migrate Entra ID, SharePoint, OneDrive, and Teams, so you can manage mailbox and content migrations in one place.

Yes, when in-place archive mailboxes are present in the source tenant, ShareGate detects them during planning and migrates archive content alongside primary mailboxes as part of the same migration flow.

ShareGate migrates the mailbox content and behaviors users rely on every day—messages, calendars, contacts, junk mail, and deleted items.

Mailbox types include user, shared, Microsoft 365 Group, room, and equipment mailboxes, with in-place and auto-expanding archive mailboxes migrating alongside primary mailboxes as part of the same flow.

Behaviors including server-side rules, automatic replies, and Litigation Hold configuration migrate with the mailbox so enforcement doesn't lapse at cutover.

Recurring meetings follow Exchange Online rules at the destination, and new Teams meeting links are created automatically.

Recurring meetings follow Microsoft-defined Exchange Online behavior after migration. ShareGate aligns mailbox data to those rules so post-cutover behavior is consistent with how Exchange Online handles recurring events.

Delegate relationships depend on both the delegator and delegate mailboxes being migrated. ShareGate's planning visibility surfaces these dependencies before execution so nothing gets missed.

Shared mailboxes migrate as part of the same workflow as user mailboxes, with no separate licensing or configuration required.

Room and equipment mailboxes migrate with their booking policy settings intact, so conference rooms are bookable from day one in the destination tenant.
