Company aquisition with another 365 tenant
Hello folks
Our business >1400 employees has bought out another business >500 employees as we are the group business we will want to onboard these users and data Sharepoint/Teams/OneDrive and Exchange mail + archives at somepoint this coming year to our tenant.
I have some questions around this:
1, What are the best practices for merging these 2 tenants, are there any guides or 3rd party SW that can assist with moves?
2, Some of the other businesses users have a need to access a shared mailbox on our current tenant, is this possible without having to create them a new user account on the main tenant as we are already paying for Lic's on the other side? can external guest access be somehow used?
Thanks for any input
Hi jsouter,
For Cross tenant mailbox migration I always use the MS solution:
https://learn.microsoft.com/en-us/microsoft-365/enterprise/cross-tenant-mailbox-migration?view=o365-worldwide
I know that there're a lot of tools out there that can do that, but this process is quite easy and I performed many migrations without issues.
For Teams, ODB, SPO... The tool that I tested more and know that works quite good is ShareGate:
https://sharegate.com/get/tenant-to-tenant-migration?gad=1&gclid=EAIaIQobChMIluCH9Z3F_gIVBNDtCh1cBw3qEAAYASAAEgKC7_D_BwE
Again, there're much more ones out there, but I have no personal experience with those ones.
Regarding your second question... Unfortunately that's not possible. An alternative could be create a Microsoft 365 Group. You can find more info here: https://learn.microsoft.com/en-us/answers/questions/432464/how-to-give-access-to-a-shared-mailbox-for-a-guest
