Hi,

 

We have our domain configured on GoDaddy and have O365 tenant with mailboxes in use. Recently we have implemented BC in a new D365 tenant, and want to migrate the mailboxes. Can anyone guide me how to achieve the same for migrating 25 mailboxes and a rough estimate for the same.

 

Thanks,

 configure the MX record on the 365 admin console first, If their email is in PST files, then all they need to do is create a new Outlook profile connected to their Exchange Online mailbox and include the PST files in that profile. They'll be able to send and receive email via Exchange Online and still have access to the old messages in the PSTs.

Microsoft doesn't provide any tools for this scenario. You either need to export/import manually via PST files, or use third-party tools.
