I am looking for a reliable way to move shared mailboxes from one Microsoft 365 tenant to another without losing important business conversations or disrupting access for employees. Shared mailboxes are commonly used by support teams, sales departments, HR, and other business units, so maintaining their existing communication history is important during tenant consolidation.
One thing I am unsure about is how to handle mailbox permissions and user access after the transfer. Moving mailbox content alone may not be sufficient because the destination environment also needs the appropriate user accounts and access permissions. I would also like to preserve folder structures, attachments, and other mailbox information during the process.
I think it is better to review the source shared mailboxes first, prepare corresponding destination accounts, and test the migration with a smaller mailbox before processing the complete environment. This can help identify account mapping issues and reduce unexpected problems during the actual transfer.
For organizations managing several mailboxes, a dedicated tenant to tenant migration tool can simplify the transfer process. I came across the SysInfo Microsoft 365 Tenant to Tenant Migration, which supports Exchange mailbox migration between Microsoft 365 tenants along with other workloads such as SharePoint, OneDrive, and Teams.
The office 365 tenant to tenant migration tool also offers mailbox mapping, incremental migration, duplicate detection, and selective migration options. These features can be useful when transferring shared and regular mailboxes as part of a larger tenant consolidation project.
The sysinfo tenant to tenant migration tool is another option worth evaluating when planning cross-tenant data transfers.
