Please pardon me for posting this kind of question. I found some post with similar issues but my problem has something different that made me create another thread.
We have this existing client that has 7 separate O365 tenants. They decided to separate the tenants because of the 300 license limitation for Business Premium plans.
These tenants have different domains and different set of users. However, they are now requesting that all of the users from these 7 tenants will be able to see each other in the Global Address List.
I have read that this is not possible but I really need to know what are my options in this scenario.
Client has a single Active Directory on-premise that contains all the users from these 7 tenants. Also, they are NOT using Exchange On-premise.
Thanks in Advance

You can create contacts to in each tenant regarding the other users to have them on the GAL, you cannot sync the same object to different tenants.

Yes, this is the first thought that came in my mind when this concern came in. However, maintaining 300 users in 7 tenants is not practical to do. Because if there is any change in one user, I have to change it across the 7 tenants.

Thanks @adam deltinger .
Is it safe to say that Microsoft's current technology does not support this kind of scenario? Do I really need to use a 3rd party system?

@almarlibetarioone good solution I know about is https://cirasync.com/support/office-365/how-to-sync-exchange-mailbox-contacts/
however am thinking out loud 7*1*250 (average users per tenant) = 1750 $/month
