We are acquiring a small company with a cloud only tenant (25 users). We have created the user accounts in our AD with a new email address/domain. We will be joining them to our domain and migrating their email, calendars, sharepoint, onedrive, etc to our tenant. What is the easiest way to do this with without spending a lot if any money. I do not see the 'cross-tenant" option under migration in our exchange portal. So far it seems the only option is to export to a pst. We only have E2 and Azure Information protection P1 licenses. They will get MS 365 business standard
Thanks in advance

    Hi @jennylee ,
    Considering that you only need to migrate 25 users,, I think exporting the mailbox to a .pst file is the quickest way.
    In addition, if you want to learn about other migration methods, Microsoft recommends that you use a third-party migration tool for migration.
    For more information you could refer to: How to migrate mailboxes from one Microsoft 365 or Office 365 organization to another

    The easiest way? get onedrive and sharepoint with "mover.io"

    The user could just export the mailbox from outlook and safe is as an .pst file.

    If the new accounts are ready, they just have to login to their new email adress and import their pst mailbox... thats all.

    it is fairly easy for the users, they just have to click "file" and then click on the export menu. If you create them 2-3 screenshots they should all get this done by themself.
