  • O365 Tenant B in US with close to 500 User/Mailboxes/ODFB and a mix of E1, E3 Licenses -Domain name is


  • to use only one Tenant to manage all 4500+500 in India+US with their user accounts, mailboxes & ODFB data as well as both the & domain in India O365 Tenant A
  • Use Multi-Geo Feature/functionality within India O365 Tenant A to host Mailboxes/ODFB data of some US users in US Data-centers

Hi @Yatin Ramnath Naik


You will need to migrate all from Tenant B to A to accomplish your goals.
