Share address book from one to other tenants in O365
- With that said, feel free to vote on the uservoice for sharing GAL between tenants! Quite a big one!

Dear Admin.,
Thank for your advises.
From your link. I know that, I need share address book to external. But, O365 do not support share address book, to do that, we need have a tool from third-party.
How to do that, my customer, they want us provide a solution for that?, So can we share address-book in O365 at the moment.
Thank you so much.,

I would suggest them to create contacts in their tenant or use B2B:

- On this page, we've implemented B2B, but cannot seem to find any intel on how to share GAL's between our two tenants. We are splitting our organisation, so this is the reason, to easily share the e-mailaddresses between the two existing tenants.
Do you have any doc's around how to do it for 2 companies that are merging? We are buying a company and I see how to setup shared free/busy but not contact list.
We will eventually use bitTitan to migrate the users to 1 main tennant but for now I would like to shared GAL and Cal not just CAL..
I was going to do this manually with CSV files for the time being but if there is an easier way that would be great.Hi CarlosSolrac did you ever get it to work for your 2 merging companies?
Do you have any documentation you could share?
Thank you

Mirela_MM what I ended up doing was this:
I enabled the free/busy sharing via the documented MS way. I then created a contact for every user in the new company in the existing company and vice versa so it is a date and time solution, it solved my problem as we only needed about 30-45 days to move all the users.I hope that helps.
